Audio System

System Description

The audio unit acts as the ‘‘processor’’ for all audio functions. Select audio functions from the audio unit, the audioremote (on the steering wheel), or by using the navigation voice control system. The audio display provides thecurrent audio status. For vehicles with navigation, additional audio information is available by touching the audiobutton on the Navigation Audio Screen. (See the owner’s manual and the navigation user’s guide for more details.)

The XM receiver passes its signal to the audio unit. In addition, it communicates with the audio unit via the GA-Net bus.Any open connections in the GA-Net bus circuit will cause audio and navigation functions to appear inoperative.

For vehicles with navigation, pressing the ‘‘open/close’’ switch on the navigation display panel allows access to the CDslot and PC card.

A security signal is daisy-chained between the audio and vehicle components for integration into the vehicle’s securitysystem.

The audio systems are equipped with speed-sensitive volume compensation (SVC). The navigation or audio unitreceives the vehicle speed pulse (VSP) from the PCM. The system processes the speed input and increases thenavigation or audio system volume level as the vehicle speed increases to compensate for the various interior noisesthat occur at higher speeds. When the vehicle slows down, the volume returns to its normal level. Then SVC has foursettings: SVC OFF, LOW, MID and HIGH that can be adjusted using the navigation or audio unit. The SVC comes fromthe factory with the MID setting as the default.

To change the audio unit SVC setting, press the ‘‘tune folder sound’’ knob repeatedly until the SVC is displayed. Rotatethe knob to adjust the SVC to the desired setting (SVC OFF, LOW, MID, or HIGH).

To change the navigation unit SVC setting, press the AUDIO button, and then select the SOUND icon on the navigationdisplay. Press the navigation display to select the desired setting (Off, Low, Mid, Hi).

The navigation system allows voice control for the audio, XM, PC card, and CD player. The GA-Net (audio unit)communicates the voice control commands. When using the TALK/BACK button, the audio is muted on all speakersand you hear navigation sound on the front channels. When using the navigation or route guidance (RG), the front speakers provides the navigation sound and the rear speakers continue to play. For more information, see the section. The outline of the interruption function is shown in this table.

The GA-Net bus passes audio and navigation commands throughout the navigation and audio components.These commands include navigation touch screen and hard button signals, audio/XM selections by voice, and XMstation and music title names. Because the entire bus is ‘‘daisy chained’’ between components (see diagram), anyopen or short in the GA-Net bus harness will cause any or all of these functions to become inoperative. The addition ofany audio accessory must maintain the continuity of the GA-Net bus by installing the ‘‘Y’’ cable included with theaccessory kit.

Error Codes

The audio system displays error codes when a problem is detected with the CD disc changer, the audio disc, or theanti-theft code.

(CD) DISC ERROR Cannot read disc. Eject the disc and try another one.DISC ERROR There is a problem with the disc

player. A common problem isdisc labels coming off the discwhile in the player.

Try to eject the disc and try another one. Ifthere is still a problem, replace thenavigation unit or audio unit.

(CD) HEAT ERROR Disc player is hot. This canhappen if the vehicle is parkedout in the hot sun all day.

Park the vehicle in a cooler place for a whileand try the disc player again. If the errorcode is still present, try another disc. If theerror code is still present, replace thenavigation unit or audio unit.

CODE ERROR E Anti-theft code mismatch(1 try).

Enter the correct anti-theft code.

CODE ERROR 1 Anti-theft code mismatch(10 try).

Remove fuse No. 23 (10 A) in the under-hoodfuse/relay box, then reinsert it. You will have10 more tries to enter the correct anti-theftcode.

(CD) Focus Error Possibly DVD inserted in unit, orCD installed upside down.

Eject CD and try a known-good CD.

Mech Error There is a problem with themechanism. A CD label may bejammed in the mechanism.

Replace the audio unit or navigation unit

Focus Error The system cannot read the discbecause an audio or video DVDis inserted into the unit. If theCD was inserted upside down,turn it over.

Verify that the unit functions with a standardmass production CD.

Heat Error CD player is too hot. This canhappen if the vehicle is parkedin the hot sun all day and iswarmer than 104 F.

The unit should function normally when itcools off, and internal temperature is lessthan 104 F.

File Error The audio unit cannot read thefiles on the CD or CD-R.

Verify that the files names end in ‘‘CDA’’(WAV for CD copies), and ‘‘MP3’’ or ‘‘WMA’’for compressed audio files on a CD-R.

(XM) OFF AIR XM channel not in service. Try another XM channel.(XM) NO SIGNAL Loss of signal. Both terrestrial and satellite antennas have

lost signal. Park the vehicle outside with aclear view of the southern horizon.

(XM) UPDATING XM radio is receivinginformation update from thenetwork.

This message will disappear once the updatefinishes.

(XM) CHECK ANTENNA XM antenna error. Repair open or short in the satellite antenna.Substitute the XM antenna with a known-good one, and recheck. If the error is gone,replace the original XM antenna. If the erroris still present, replace the antenna lead.

(XM) ANTENNA ERROR

No signal from XM. Check a known-good vehicle with XM radio.If the known-good vehicle has the samesymptoms, contact XM Satellite radio at(800) 852 9696.

• Make sure the CD disc is compatible with the system(see the owner’s manual for more information).

1. Press the OPEN/CLOSE button to open thenavigation display.

2. Try inserting an audio CD.

The system is OK at this time.

Go to step 3.

3. Press the CD eject button.



Unfortunately there are no error messages and nodiagnostics for the PC card. There are many reasonswhy a card won’t play audio files in the audio unit.• The card may not be fully inserted into the slot. Eject

the card, and inspect for warping or damage to theedge connector. Never use excessive force to insert acard. This can result in damage to the pins in the rearof the slot.

• The customer’s card may contain audio files that arenot recognized by the system. Only MP3 and WMAmusic files are played.

• The flash card type may not be accepted by thesystem. Only Compact Flash, SD, and ATA cards havebeen tested.

• The card’s PCMCIA adaptor may be preventing aknown-good card from playing. New PCMCIAadaptors are constantly being released, and have notbeen tested.

• The card’s capacity may exceed 1 GB. Only cardswith capacities of up to 1 GB (1000 MB) have beentested.

• There may not be any files on the card. Of the cardhas ‘‘write protection,’’ make sure it is turned offbefore putting files on the card.

• Although flash memory chips are reliable,occasionally they develop bad sectors or otherformatting errors that prevents them from playing.The customer should re-format the card using theFAT or FAT32 format.

• The card may have been damaged by heat. Suggestthat the customer remove their card when exiting thevehicle.

• The customer may have formatted the card using theNTFS format. Only the FAT and FAT32 formats areaccepted by the system.

• Hard disc drive (HDD) cards may not work properly inthe system and can overheat and quit functioning,particularly in a hot vehicle. They are notrecommended.

• The filing structure of the card may exceed thespecification of 8 folder levels deep, 99 foldersmaximum, and 999 total tracks maximum. If any ofthese limitations is exceeded, the system may notproperly display or play the tracks.

NOTE: A delay when first inserting a card is normal.The system is reading the ‘‘File Tag’’ information foralbum names, artist, and song titles and there is no‘‘hour glass’’ The delay length depends on the numberof tracks and the complexity of the folder structure.See the audio section glossary for an explanation of theterms used above.

Does the player except the CD?

Use the following tests to check sound quality.

NOTE: Before beginning the following tests, write downthe bass, treble, fader and balance settings, and thenset them to their center positions for testing.

Do this test to confirm proper channel routing.

1. Insert the audio diagnostic CD (T/N 07AAZ-SDBA100) into the navigation unit or audio unit.

2. Play track No. 1 (left, both, right channel ID) at anormal, or slightly higher than normal, volumelevel.

3. The voice should be audible only from the channelor channels when indicated.

• If the channel ID is correct for each side, go to thephase test.

• If the channel ID is not correct, check for;– Shorted speaker wire– Faulty navigation unit– Faulty audio unit


Do this test to confirm proper speaker phasing.


2. Play track No. 2 (phase) at a normal, or slightlyhigher than normal, volume level.

3. The voice should sound centered and focusedwhen it is in-phase.

4. The voice should sound diffused, and have ‘‘lessbass’’ when it is out of phase.

• If the voice changes from in-phase to out ofphase as indicated by the prompt, the phasing iscorrect. Go to electrical noise test.

• If the voice always sounds out of phase, phasingis not correct. Check for;– Crossed speaker wires– Faulty navigation unit– Faulty audio unit

Do this test to check for electrical noise being inducedinto the audio system.

NOTE: Electrical noise may be caused by outsidesources that cannot be prevented by the audio system.Make sure you remove any cell phones and/or turn offany aftermarket device before beginning this test.


2. Play track No. 4 (digital zero) at a normal, or slightlyhigher than normal, volume level.

3. Operate any electrical device that may createelectrical noise in the audio system, includingstarting the engine.

4. Play track No. 5 (near digital zero) at a normal, orslightly higher than normal, volume level.


6. Play track No. 6 (SNR) at a normal, or slightlyhigher than normal, volume level.


• If no abnormal noise is heard, go to individualspeaker test.

• If the noise is present only during the SNR track,replace the navigation unit or audio unit.

• If the noise is heard during the digital zero ornear digital zero track, check for;– Poor ground for the audio unit, engine or

battery cable– Pinched or shorted speaker wire– Faulty navigation unit– Faulty audio unit– Other faulty components causing excessive

electrical noise (ignition coils, alternator, doorlock actuators, etc.). Disconnect any suspectcomponents, and then replay the tracks thatwere originally noisy. If the noise is gone,check the component’s circuit and thecomponent.

2. Play track No. 30 (steady 300 Hz tone) at a normal,or slightly higher than normal, volume level.

3. Listen to each speaker for poor sound compared tothe other speakers. Use the audio unit’s fader andbalance settings to help isolate the channel with theproblem.

• If the sound quality produced by a specificspeaker is poor, substitute it with a known-goodspeaker. If the poor sound quality continues, goto the sound balance test.

• If the sound quality is OK, go to the soundbalance test.


Perform this test to identify a faulty channel or speaker.


2. Confirm the bass and treble are set to the centerpositions.

3. Play track No. 3 (pink noise) at a normal, or slightlyhigher then normal, volume level.

4. A ‘‘static’’ type sound should be heard through allspeakers.

5. Insert the audio diagnostic CD (T/N 07AAZ-SDBA100) into the navigation unit or audio unit of aknown-good vehicle.

6. Set the bass and treble to the center position.

7. Play track No. 3 (pink noise) all the same level aswas played in step 3.

8. Compare the sounds made by the two vehicles.

• If the sounds made by the two vehicles are verysimilar, go to the Frequency Sweep Test(see page 23-57).

• If the sound does not have as much bass, checkthe subwoofer and circuit.

• If the sound does not have enough ‘‘hiss,’’ checkthe tweeters and their circuits.

Frequency sweep Sound judging

23-5723-57


Do this test to find rattles or reverberations that maycause a perception of poor sound quality.


2. Play track No. 13 (sweep from 500 Hz to 35 Hz) at anormal, or slightly higher than normal, volumelevel.

3. Listen to each speaker for poor sound quality orreverberations caused by specific frequencies. Usethe voice-over to estimate the frequency thatcauses the vibration. Use the audio unit’s fader andbalance settings to help isolate the channel with theproblem.

• If vibrations or poor sound quality are heard, goto step 4.

• If no vibrations or poor sound quality are heard,go to sound judging.

4. Choose the appropriate track from No. 14 to 25(small range frequency sweep) or 26 to 53 (singlefrequencies) to recreate the frequency that causedthe poor sound quality or vibration located in step3: this aids in diagnosis of the cause.

NOTE: When you get to the track that recreates theproblem, select the repeat function on thenavigation unit or audio unit, this will help youisolate the cause.

5. Replace or insulate the source of the vibrations or,if the speaker is the source of the poor soundquality, replace it.


• Do this test to compare overall sound quality,imaging, and dynamics between the customer’svehicle and a known-good vehicle. Only use a vehicleof the same model and trim level for this test.

• Make sure the vehicle is using only OEM speakers.

1. In the customer vehicle, set the bass, treble, fader,and balance settings to the customer’s normalsettings that were written down before beginningtesting.


3. Play tracks No. 7 to 12 (sound quality, midland,dynamics, and imaging demonstration tracks) at anormal, or slightly higher than normal, volumelevel. Write down the volume setting being used.

4. Listen to areas of the track that stand out as beingeither very clear or poorer than other areas of thetrack.

5. Insert the audio diagnostic CD (T/N 07AAZ-SDBA100) into the navigation unit or audio unit of aknown-good vehicle.

6. Play the tracks at the same volume level and thesame bass, treble, balance, and fader settings asused in step 3 in the customer’s vehicle.

7. Listen to the same area of the track that stood outas being either very clear or poorer than otherareas of the track.

Navigation System

General Troubleshooting Information

Refer to the Honda Navigation System manual, for thenavigation system operating procedures.

The navigation system has a coded theft protectioncircuit. Make sure you have the customer’s anti-theftsecurity code before;

• Disconnecting the battery• Disconnecting the navigation unit 12P and 17P

connector• Removing the No. 23 (10 A) fuse from the under-hood

fuse/relay box

After service, reconnect power to the navigation unit,and turn the ignition switch ON (II). Enter the 4-digitanti-theft security codes, then select ‘‘Done.’’

When replacing the navigation unit, be sure to give thecustomer the new anti-theft security code.

Certain circumstances and system limitations will resultin occasional vehicle positioning errors. Somecustomers may think this indicates a problem with thenavigation system when, in fact, the system is normal.Keep the following items in mind when interviewingcustomers about symptoms of the navigation system.

The limitations of the self-inertial portion of thenavigation system (the yaw rate sensor and the vehiclespeed signal) can cause some discrepancies betweenthe vehicle’s actual position and the indicated vehicleposition (GPS vehicle position).

The following circumstances may cause vehiclepositioning errors:

• Moving the vehicle with the engine stopped and thevehicle stopped, such as by ferry or tow truck, or ifthe vehicle is spun on a turn table.

• Tire slippage, changes in tire rolling diameters, andsome driving situations may cause discrepancies intravel distances. Examples of this include:– Continuous tire slippage on a slippery surface.– Driving with snow chains mounted.– Abnormal tire pressure.– Incorrect tire size.– Frequent lane changes across a wide highway.

– Continuous driving on a straight or gently curvinghighway.

• Tolerances in the system and map inaccuracies willsometimes limit how precisely the vehicle position isindicated. Examples of this include:– Driving on roads not shown on the map (map

matching is not possible).– Driving on a road that winds in one direction, such

as a loop bridge, an interchange, or a spiral parkinggarage.

– Driving on a road with a series of sharp hair-pinturns.

– Driving near a gradual highway exit or transition.– Driving on one of two close parallel roads.– Making many 90 degree turns.– The direction to destination icon or ‘‘Destination

icon’’ shown or the map may be up to severalhundred feet away from the actual location.

The GPS cannot detect the vehicle’s position during thefollowing conditions:

• For the first 5 to 10 minutes after reconnecting thebattery (this can take as long as 45 minutes).

• When the satellite signals are blocked by tallbuildings, mountains, tunnels, large trees, or largetrucks.

• When the GPS antenna is blocked by an object placedabove it in the vehicle. The GPS antenna requires aclear unobstructed view of the sky.

• When the satellite signals are blocked by theoperation of some electronic aftermarket accessoriesincluding, but not limited to non-OEM in-dashentertainment units (radio, CD players/changers, andLo Jack), cell phones placed near navigation systemand window tinting above the GPS antenna.

The accuracy of GPS is reduced during these instances:

• When only three satellite signals can be received(Four satellite signals are required for accuratepositioning).

• When the satellite control centers are experiencingproblems.

• When driving near high tension power lines.

23-67

Whenever the navigation system is giving guidance,the front speakers are muted. When the voice controlsystem is being used, all of the speakers are muted.

• In cold temperatures, the display may stay dark forthe first 2 or 3 minutes until it warms up.

• When the display is too hot because of direct summersunlight, it will remain dark until the temperaturedrops.

• When the humidity is high and the interiortemperature is low, the display may appear cloudy.The display will clear up after some use.

• Fingerprints on the touch panel may sometimes benoticeable because of the panel’s low-reflectioncoating. Clean the screen with a soft damp cloth. Youmay use a mild cleaner intended for eye glasses orcomputer screens. To avoid scratching the panel, donot rub too hard, or use abrasive cleaners, or shoptowels.

• The touch panel uses a resistive membrane, that isunaffected by sunlight. If a touch switch does notfunction immediately, shift your finger slightly, andtouch it again.

• If you can duplicate the symptom, compare it to a‘‘similar known-good vehicle. ’’Only use a vehicle ofthe same model, same year, same trim, and samesoftware version. If you can duplicate the symptom inthe like known-good vehicle, then it is a characteristicof the system.

• When the symptom can be duplicated, follow the self-diagnostic procedures and the appropriatetroubleshooting procedures.

• When the symptom does not reappear or onlyreappears intermittently, ask the customer about theconditions when the symptom occurred.– Try to establish if outside interference may be the

cause.– Try to duplicate the symptom under the same

conditions the customer experienced.– Vibration, temperature extremes, and moisture

(dew, humidity) are factors that are difficult toduplicate.

– Inspect the vehicle for aftermarket electronicdevices (vehicle locators, radar detector amps, etc.)that may be hidden.

• Check for service bulletins or Service News articlesthat may relate to the customer’s concern.

• Before disconnecting the battery, make sure youhave the anti-theft code for the navigation system,and write down the audio presets.

• The navigation unit is located in the dashboard.• When the battery is disconnected, the internal GPS

clock is reset to ‘‘0:00.’’ The clock will reset to thecorrect time after the system finishes the GPSinitialization.

• After reconnecting the battery, you have to wait to getthe initial signal from the satellite. It will take from 10to 45 minutes.

• Before returning the vehicle to the customer, enterthe navigation anti-theft security code, then enter theaudio station presets.

If for any reason, you lose power to the navigationsystem (like the battery was disconnected), thenavigation system will require initialization. Oncecompleted, your system will be ready to use.

This initialization requires the following:• Entering the 4-digit navigation anti-theft security code

to ‘‘unlock’’ the system• GPS initialization (may not be needed depending on

the length of time the system was without power)• Map matching to align the GPS to a location on the

map

The navigation system has a coded theft protectioncircuit. Be sure to get the customer’s anti-theft securitycodes number before;• Disconnecting the battery• Disconnecting the navigation unit 17P connector• Removing the No. 23 (10 A) fuse from the under-hood

fuse/relay box

After service, reconnect power to the navigation unit,and turn the ignition switch ON (II). Enter the 4-digitanti-theft security code, then select ‘‘Done.’’When replacing the navigation unit or audio unit, besure to give the customer the new anti-theft securitycode.

When inside the shop bypass the GPS acquire screens,pressing and holding the ‘‘Menu,’’ and ‘‘Zoom out’’keys at the same time. Touch the ‘‘Return’’ button onthe screen to exit the diagnostic mode. This allows youto continue troubleshooting while in the shop.

If the navigation system finds the satellites properly,this box clears, and changes to the Disclaimer screen. Ifwithin 10 minutes the system fails to locate a sufficientnumber of satellites to locate your position, thefollowing screen appears.

After 30 minutes with this screen displayed, turn off theengine, then restart the vehicle. If you now see theDisclaimer screen, the GPS initialization is complete.

NOTE:• The average acquiring time is less than 10 minutes,

but it can take as long as 45 minutes.• If the system is still unable to acquire a signal, follow

the instructions on the screen. If this screen appearsagain, go to troubleshooting for the GPS icon is whiteor not shown (see page 23-92).

• Park the vehicle in an area where the GPS satellitesignals will be unobstructed, and check the satellitemark on the display.

• Drive the vehicle 1 mile before entering a destinationand confirm the road being used is displayed at thebottom of the screen (map matched).

• Enter the dealer address and confirm the systemroutes and performs normally.

• Clear any previous destinations and address entriesthat may have been entered for testing purposes.

Overview

System Description

The navigation system is a highly sophisticated, hybrid locating system.

The navigation unit uses global positioning system (GPS) satellite signals, internal yaw and vehicle speed inputs, anda map database to show where the vehicle is and to help guide you to a desired destination.

The navigation unit’s GPS receiver receives signals from the GPS, a network of 24 satellites in orbit around the earth.By receiving signals from several of these satellites, the navigation system can determine the latitude, longitude, andelevation of the vehicle.

Signals from the system’s yaw rate sensor (inside the navigation unit) detects turns, and the PCM vehicle speed pulse(VSP) and reverse signal enable the system to keep track of the vehicle’s speed and direction of travel. The advantageof this hybrid system is that the system can track your position if either the GPS signal or the vehicle speed signal ismissing. For instance, when in a tunnel (no GPS), the speed signal is used to update your position on the map.Alternately, while the vehicle is being transported on a ferry, GPS signals can show the vehicle position on the map asit crosses the water.

The navigation system uses the location, direction, and speed information to display the appropriate map andcalculate a route to the destination entered. As you drive to a destination, the system provides both visual and audioguidance. Audio guidance is sent to the audio unit, and an RGB graphics color signal is sent to the navigation display.

This navigation system also has voice recognition that allows voice control of most of the navigation, and audiofunctions. The voice control switches (TALK and BACK buttons on the steering wheel) activate the voice controlsystem. The microphone on the ceiling receives your voice commands. For more information on this feature, consultthe navigation owner’s guide.

The illumination signal is used by the navigation unit to automatically switch the display mode between the ‘‘Night’’and ‘‘Day’’ display modes. When the headlights are on, the dash brightness control setting ‘‘full brightness’’ overridesthe ‘‘Night’’ display mode, and allows a daytime navigation display with the lights on.

When the navigation system is giving voice guidance commands, the front speakers are muted. When the voicecontrol system is being used (TALK button pressed), all of the speakers are muted.

The internal GA-Net II bus passes information back and forth between the navigation display, the navigation unit, andthe audio system components. The information passed on this bus are touch button commands, audio muting signal,audio (radio and XM), and any open in these bus lines can affect the navigation system or other audio accessoryoperation.

The clock on the navigation display is set and maintained by the navigation unit. The time is automatically adjusted fordaylight savings, and time zone changes while driving. The time can be adjusted in setup.

Additional information is available about the navigation components following the System Diagram. A glossary ofterms that are used throughout this section follows the detailed information.

The Navigation System manual in the glove box covers all of the system functions and settings. Use this as a resourcewhen evaluating a customer concern.

Sensor element top view

The yaw rate sensor (located in the navigation unit) detects the direction change (angular speed) of the vehicle. Thesensor is an oscillation gyro built into the navigation unit.

The sensor element is shaped like a tuning fork, and it consists of the piezoelectric parts, the metal block, and thesupport pin. There are four piezoelectric parts: one to drive the oscillators, one to monitor and maintain the oscillationat a regular frequency, and two to detect angular velocity. The two oscillators, which have a 90-degree twist in thecenter, are connected at the bottom by the metal block and supported by the support pin. A detection piezoelectric partis attached to the top of each oscillator. The driving piezoelectric part is attached to the bottom of one oscillator, andthe monitoring piezoelectric part is attached to the bottom of the other oscillator.

The piezoelectric parts have ‘‘electric/mechanical transfer characteristics.’’ They bend vertically when voltage isapplied to both sides of the parts, and voltage is generated between both sides of the piezoelectric parts when they arebent by an external force. The oscillation gyro functions by utilizing this characteristic of the piezoelectric parts and‘‘Coriolis force.’’ (Coriolis force deflects moving objects as a result of the earth’s rotation.) In the oscillation gyro, thisforce moves the sensor element when angular velocity is applied.

1. The driving piezoelectric part oscillates the oscillator by repeatedly bending and returning when an AC voltage of6 kHz is applied to the part, The monitoring-side oscillator resonates because it is connected to the driving-sideoscillator by the metal block.

2. The monitoring piezoelectric part bends in proportion to the oscillation and outputs voltage (the monitor signal).The navigation unit control circuit controls the drive signal to stabilize the monitor signal.

3. When the vehicle is stopped, the detecting piezoelectric parts oscillate right and left with the oscillators, but nosignal is output because the parts are not bent (no angular force).

4. When the vehicle turns to the right, the sensor element moves in a circular motion with the right oscillatorbending forward and the left oscillator bending rearward. The amount of forward/rearward bend varies accordingto the angular velocity of the vehicle.

5. The detecting piezoelectric parts output voltage (the yaw rate signal) according to the amount of bend. Theamount of vehicle direction change is determined by measuring this voltage.

Navigation System


The global positioning system (GPS) enables the navigation system to determine the current position of the vehicle byusing the signals transmitted from the satellites in orbit around the earth. The satellites transmit the satelliteidentification signal, orbit information, transmission time signal, and other information. When the GPS receiverreceives a signal from four or more satellites simultaneously, it calculates the current position of the vehicle based onthe distance to each satellite and the satellite’s positions in its respective orbit.

The precision of the GPS varies according to the number of satellites from which signals are received and the view ofthe sky. The precision is indicated by the color and shape of the GPS icon shown on the display.

No GPS icon shown 2 or less Impossible to detectvehicle position

GPS function is normal.The satellite signals received bythe GPS are too few to detect thevehicle position.

The longitude, latitude and thealtitude of the vehicle position canbe detected. (More precise thandetection in two dimensions)

The GPS antenna amplifies and transmits the signals received from the satellites to the GPS receiver.

The GPS receiver is built into the navigation unit. It calculates the vehicle position by receiving the signal from the GPSantenna. The vehicle position and signal reception condition is transmitted from the GPS receiver to the navigationcontrol unit to adjust vehicle position.

The navigation unit calculates the vehicle position and guides you to the destination. The unit performs map matchingcorrection, GPS correction, and distance tuning. It also controls the menu functions and the DVD-ROM drive, andinterprets voice commands. With control of all these items, the navigation unit makes the navigation picture signal,then it transmits the signal to the navigation display and audio driving instructions to the audio unit.

The navigation unit calculates the vehicle position (the driving direction and the current position) by receiving thedirectional change signals from the yaw rate sensor and the travel distance signals from the PCMs vehicle speed pulse(VSP) signal.

The map matching tuning is accomplished by indicating the vehicle position on the roads on the map. The map datatransmitted from the DVD-ROM is checked against the vehicle position data, and the vehicle position is indicated onthe nearest road. Map matching tuning does not occur when the vehicle travels on a road not shown on the map, orwhen the vehicle position is far away from a road on the map.

The GPS tuning is accomplished by indicating the vehicle position as the GPS’s vehicle position. The navigation unitcompares its calculated vehicle position data with the GPS vehicle position data. If there is large difference betweenthe two, the indicated vehicle position is adjusted to the GPS vehicle position.

The distance tuning reduces the difference between the travel distance signal from the VSP and the distance data onthe map. The navigation unit compares its calculated vehicle position data with the GPS vehicle position data. Thenavigation unit then decreases the tuning value when the vehicle position is always ahead of the GPS vehicle position,and it increases the tuning value when the vehicle position is always behind the GPS vehicle position.

The navigation unit can calculate different routes to a selected destination. You have five options:• Direct Route Calculate a route that is the most direct.• Easy Route Calculate a route that minimizes the number of turns needed.• Minimize Freeways Calculate a route that avoids freeway travel. If that is not possible, keep the amount of

freeway travel to a minimum.• Mimimize Toll Roads Calculate a route that avoids, or minimizes travel on toll roads.• Maximize Freeways Calculate a route that uses freeways as much as possible.

The navigation unit transmits audio driving instructions before entering an intersection or passing a junction.The audio instructions come through the audio unit to the front speakers.

NOTE: The front speakers are muted whenever the navigation system is giving guidance commands, and all of thespeakers are muted when the voice control system is being used.

The map data (including all scale rates) is stored in the DVD-ROM. The map data includes:• Road distances, road widths, speed limits, traffic regulations, passing time at junction, distances to junctions, and

the driving instructions for audio guidance.• Latitude and longitude GPS.

The system is in a‘‘Detecting’’ mode, and is waiting for all items inwhite to be tested. This includes the voice controlswitch (TALK/BACK buttons), and the microphone.Press and release the TALK button on the steeringwheel, and in a normal voice, say ‘‘testing.‘‘ The Talkindicator on the screen should turn green, and thevoice level indicator should move to at least the 6thbar to pass. Next, press the BACK button. The‘‘Cancel‘‘ indicator should turn green.

• If all of the communication lines connecting thesystem components, and the TALK/BACK buttons/microphone check out OK (all block diagram itemsgreen), then the ‘‘OK’’ indicator turns green.

• If there is a problem with the system, the faultysystem component item turns red, and the screen willshow ‘‘NG’’ in red. Use the troubleshooting index,and other diagnostic screens to help locate theproblem.

• The indicator on the screen may not change until youcycle the ignition switch. After repairing the affectedcable or system, repeat this diagnostic.NOTE: Green boxes and green ‘‘OK’’ indicate that thecommunications lines (cables) are intact. Thisdiagnostic does not necessarily imply that theindividual components are functioning properly. Forinstance, the GPS antenna wire may be crushed, butstill show as ‘‘green.’’ A road test, or other diagnosticmay be necessary to find the problem.

• Select ‘‘Return’’ to return to the Diagnostic Menu orthe ‘‘Exit Diag’’ button to exit.

NOTE: The Mic Level indicator must reach the 6th baror greater to pass the test.

This screen verifies that the navigation display isreceiving the video (R, G, B and Composite sync)signals properly. The three primary colors should all beshown without distortion. The combination of all threeshould produce a central white section. If any of thecolors are missing, troubleshoot for the color signal(see page 23-90). If the picture has lines in it, or scrollshorizontally or vertically, troubleshoot for a Compositesync problem (see page 23-91).

This screen looks for problems with contrast. Youshould be able to see the changes from bar to baracross the scale.

This diagnostic screen checks for pixels that may be‘‘dead’’ (off). The entire display must be white. If pixelsare ‘‘dead,’’ replace the navigation unit.

The entire display must be black. This diagnostic screenchecks for pixels that may be ‘‘stuck’’ (on). If pixels are‘‘stuck’’ on, replace the navigation unit.

The chart below shows the colors being used for theMap and Menu screens. This is for factory use only. Tocheck the color signal use the ‘‘RGB’’ test.

This allows you to center the navigation display. Usethe joystick to move the picture up/down or left/right. Itis unlikely that you will ever need to adjust the monitorposition. The ‘‘Default’’ button will reset the displayposition to factory specifications. The factory default is0, 0. The ‘‘H-POS’’ button is for factory use only.

The panel touch sensing system consists of a touchsensitive resistive membrane covering the display.Contrary to other systems using infrared beams, thescreen has to be physically ‘‘touched’’ to make it work.The display has the capability 479 locations (left toright), and 233 touch locations (top to bottom). Theupper left hand corner is position (0, 0) and the lowerright hand corner is (479, 233) as displayed. Touchinganywhere on the screen will display the ‘‘coordinate’’ ofthe location, and cause the place you touch to display a‘‘ ’’ icon. If any areas of the screen either don’trespond, or respond at some other location whentouched, then replace the navigation unit.

NOTE: Unlike earlier screens that used infrared sensors,direct sunlight will not affect this test.

NOTE: It is normal for the VOL ( , ) CH ( , ) andMODE button to be inactive.

Use this screen to confirm that navigation unit isproperly receiving input signals. Signals equal to (0) areOFF, and signals equal to (1) are ON. If the value on thedisplay does not match the actual vehicle status, thencheck the wire carrying the signal.

• VSP-Vehicle Speed Pulse from PCM connector A(Pin 13 of 17-Pin C-connector)a) OFF (0) when vehicle is not movingb) ON (1) when vehicle is moving

The VSP comes from the PCM as a dedicated signal.Internally, the navigation unit compares the actual VPon the map against street data to adjust the pulse tospeed scaling factor.

• BACK-Reverse indication from taillight relay(Pin 7 of 12-Pin C-connector)a) OFF (0) when shift lever is in any position otherthan reverseb) ON (1) when shift lever is in reverse

The Back signal is used by the navigation unit to allowthe map screen to show the VP moving backwardswhen in reverse and to trigger the optional rear viewcamera. This signal is needed because the speed pulsedoes not provide any directional information to thesystem.

• ILL CANCELa) OFF (0) when the gauge assembly brightnesscontrol is less than 90 % brightness.b) ON (1) when the gauge assembly brightness knobis more than 90 % brightness.

This screen shows the current status of GPS reception.The circular diagram shows the current location of theGPS satellites (yellow balls) as they would appear in thesky. The outer circle represents the horizon (0 degreeselevation). The middle and inner circles represents 30and 60 degrees respectively. The very center of thediagram (90 degrees elevation) is directly overhead.Nearby obstructions, like tall buildings, will blocksatellites in that direction. That is why it is necessary totroubleshoot GPS reception issues in an open area. Thesatellites shown on the diagram correspond to the‘‘PRN’’ number in the ‘‘GPS Details’’ screen. There arealways 24 ‘‘active’’ GPS satellites in orbit. Becausesatellites fail, and have to be removed from service,spares are always parked in orbit, ready to be activated.This is why the PRN (satellite ID number) can be greaterthan 24.

NOTE:• To use this screen for troubleshooting, the vehicle

should be outside, away from buildings, tall trees,and high-tension wires for at least 10 minutes withthe engine running.

• Metallic window tinting on the front or side windowor after-market electronic accessories mounted nearthe navigation unit, GPS antenna, or navigationdisplay can interfere with GPS acquisition.

• The ‘‘Number of Satellites’’ box shows the number ofacquired satellites (maximum of 12). It should containfour or more icons. If not, troubleshoot for ‘‘GPS iconis white or not shown’’ (see page 23-92).

• The ‘‘Current Position’’ shows latitude, longitude, andelevation. If there are less than four satellites, theelevation can be grossly inaccurate.

• The Date/Time field shows the current date, and alsoa time that includes daylight savings and otheroffsets entered by the customer in Setup function‘‘Adjust Time Zone/Clock.’’

By pressing and holding the MENU button for10 seconds, a GPS Detail screen is appears. This screendisplays real time incoming satellite positional data.Most of the information shown on this screen is forfactory use, however some of the data can indicatepartial GPS signal interference.

• The box TS/AS and HDop/VDop is for factory use.• The Speed and Direction information is updated in

real time when driving, and can be used to detectintermittent speed sensor problems.

• The Date/Time Information is the same as in Setupscreen 2 ‘‘Adjust Time Zone/Clock.’’

• If the ‘‘3D’’ icon is shown above the yellow dots, thisimplies that at least four satellites are available formap positioning, and the ‘‘GPS’’ indicator on the mapscreen will be green. See the Global PositioningSystem detailed explanation in the ‘‘SystemDescription’’ (see page 23-76).

• If the row of data in the table below begins with a‘‘yellow dot,’’ the AZI and EL fields can be used tolocate each satellite ‘‘PRN’’ on the circular GPSdiagram (see prior screen).

This diagnostic checks the yaw rate sensor in thecontrol unit. This device detects when the vehicle turns,and repositions the vehicle postion icon on the mapscreen. For more detailed information, see the yaw ratesensor theory of operation under ‘‘System Description’’(see page 23-75).

• ‘‘Sensor’’ indicates the voltage output from the yawrate sensor. It should indicate about 2.500 V whenstopped.

• ‘‘Offset’’ is the reference voltage or standard withinthe yaw rate sensor. It also should indicate about2.500 V when stopped.

• A ‘‘sensor’’ output voltage HIGHER than the ‘‘Offset’’voltage indicates that the vehicle is turning to theright.A ‘‘sensor’’ output voltage LOWER than the ‘‘Offset’’voltage indicates that the vehicle is turning to the left.

• The yaw rate offset and sensor should both indicateabout 2.500 V when stopped. If either reads zero or5.000 V, replace the navigation unit.

• The yaw rate offset and sensor should be within /0.01 V of each other when stopped. The sensor valueshould change relative to the offset as the car isturned while driving. If not, replace the navigationunit.

This diagnostic allows you to graphically displayproblems with the yaw rate sensor.

• The ‘‘ANG-Disp’’ value accumulates any differencesbetween the ‘‘offset,’’ and ‘‘sensor’’ voltages (seeYaw Rate diagnostic). When the sensor is healthy, therandom changes in these two voltages generallycancels out, so the value is 0. However if one voltageis consistently higher than the other, then the ‘‘ANG-Disp’’ value accumulates the constant change.

• The ‘‘Reset’’ button temporarily clears the angularaccumulation (ANG-Disp), and clears the display dots.

• Do not touch the ‘‘CCW’’ or ‘‘CW,’’ or ‘‘Set’’ buttons.These are used for factory setup only.

For serious problems with the sensor, the stationarytest usually confirms whether the sensor is defective.For yaw rate issues related to driving, perform the roadtest described below.

1. Stationary test: If the ‘‘VP’’ icon spins in place andthe ‘‘ANG-Disp’’ value slowly increases ordecreases in value, the yaw rate sensor is defective.Replace the navigation unit.

2. Road test: Drive the vehicle on a very straight road.Enter the diagnostic mode, select ‘‘Yaw rate,’’ andtouch the ‘‘Tuning’’ button. While driving down astraight road, the white ‘‘dots’’ should trace astraight line across the screen. However, if you aredriving on a straight road, and you notice the dotsconstantly dropping down or heading up as youdrive, the navigation unit’s yaw sensor is defective.You can touch ‘‘Reset’’ to clear ‘‘ANG-Disp,’’ anddotted line.

3. If either test fails, please enter ‘‘Yaw rate sensordefective’’ for the problem description, on the‘‘Navigation core return form.’’

As the vehicle moves, the navigation system receivesspeed pulses from the PCM. These pulses areconverted using a conversion factor to a mph speedthat moves the vehicle position (VP) on the map. Thenavigation system has an internal tuning function thatgenerates and refines this factor based on actualdriving. The ‘‘Level’’ indicates the status of the tuning.

• The ‘‘Auto Tuning’’ is factory set to ‘‘ON,’’ and shouldremain on.

• The ‘‘Study’’ indicates the tuning status.• The ‘‘Tire-Cal. Tuning’’ and ‘‘Set’’ should not be used.

It is for factory use only.

This screen is for factory use only. It allows adjustmentof the GPS time. This display updates in real time.

• ‘‘GPS Time’’ is the time as received from the GPSsatellites. It is in Greenwich Mean Time (GMT).

• Date, Hour, Minute, and ‘‘Set’’ should not be used.

This screen allows the navigation system to ‘‘drive’’ aroute, when the vehicle is stationary. Typicalapplications include auto shows, and other events.This feature allows a visitor to enter a destination, andsee the system ‘‘drive’’ to the destination. No speedsignal is needed.

• To initiate the mode select ‘‘ON’’.• Changing the ‘‘speed rate’’ in ms (milliseconds) is

optional, and represents the time between updates ofthe VP (vehicle position) movement.– When you increase the rate, the VP slows down

because it is updated (moved) at a slower rate.– When you decrease the rate, VP is faster because it

is updated (moved) more frequently.– 1500 ms is VP at its slowest in demo mode.– 150 ms is VP at its fastest in demo mode (Default).

• At key off, the setting automatically returns to thedefault of ‘‘Off.’’

This diagnostic screen allows you to independently testthe microphone and the TALK and BACK buttons. Theyare used to activate the voice control system. Themicrophone is located near the map light in the ceiling.It is directional, and works best if the voice is comingfrom the drivers seat.

• Press the TALK button on the steering wheel, and in anormal voice say ‘‘testing.’’ The TALK indicator onthe screen should momentarily turn green, and thetext ‘‘Now Recording...’’ should appear in yellow. Ifthe Mic Level indicator on the screen does not brieflyturn green, then check the wiring from the TALKbutton to the navigation unit. If there is no ‘‘MicLevel’’ movement when you speak, then you shouldcheck the wire running from the microphone to thecontrol unit.

• Press the BACK button on the steering wheel. Thisshould cause the Cancel indicator on the screen tomomentarily turn green. If it does not briefly changeto green, then check the wiring from the steeringwheel BACK button to the navigation unit.

NOTE:If the radio is off, and there is movement in theindicator, even without speaking, then ensure that thevents are not blowing on the microphone.This should resolve voice control complaints such as:• ‘‘Sometimes the system does not understand my

commands.’’• ‘‘I have to shout at the navi for a command to be

recognized.’’• The system just says ‘‘pardon.’’

This screen to graphically displays the sun’s position asdetermined by GPS. The climate control system usesthe navigation systems sun angle, along with thesunlight sensor to control the driver/passenger A/C airflow. The heat that the climate control unit removesvaries, depending on the angle of the sun entering thevehicle.

This screen is for factory use only, and allowssimulation of this feature for development purposes.

• The ‘‘manual tuning’’ button should always be ‘‘OFF.’’• The ‘‘Angle’’ is the angle that the sun (shown with the

red ‘‘dot’’) is above the horizon.• The ‘‘vehicle’’ value represents the angle, clockwise

from North, to the direction that the vehicle position(VP) icon is pointing (always points straight up).

• The ‘‘direction’’ value is the angle, measuredclockwise from the VP (straight up) to the sunsposition.

• The reliability ranges from 1 to 3, and represents theaccuracy of the Vehicle Position relative to the sun.

When replacing the navigation unit, this function allowsthe dealer to transfer the customer’s personal data tothe new navigation unit. The transferred informationincludes their Setup settings, and personal addresses.The dealer inserts a PC card to the navigation unit, andthen selects the ‘‘Save Users Memory’’ function.

PC Card FAQs

Question Answer

23-117

Where do we buy the flash memory oradaptors, and what do we ask for?

You need a ‘‘PCMCIA type II’’ adaptor and a flash memory chip. They canbe purchased at a computer, or office supply store. The card will havethe same size and shape as the card in the HDS. Adaptors that acceptmultiple flash types are not recommended.

What memory flash chips will workwith what adaptors?

The flash memory devices that have been tested include Compact Flash(CF), and ATA style (like the card in the HDS). Other card types and flashmemory chips may work, but have not been tested.

What capacity card do I need for thisfunction?

A memory chip with capacity of 64 MB to 2 GB will work. The two filesmoved to the PC card during ‘‘export’’ are less than a Megabyte in size.

Should the dealer have a dedicated PCcard for the Export and Importnavigation function?

Yes, treat the PC card as a dedicated ‘‘special tool’’ that should be usedanytime your ’07 or later customer needs their navigation personal filestransferred to a new navigation unit.

What device can I use to maintain thePC card, and delete files

Any computer store sells USB style card readers that accept the PC card,and allow you to perform file maintenance on your PC card. Most laptopswill also accept the PC card.

Can we move the customer’s data todifferent models?

No, the files are model specific and will only load into a navigation unitwith the same part number.

Can we move the customer’s data tothe same vehicle with a differentsoftware version?

The customer’s files can only be transferred to a new navigation unit, ifthe ‘‘Model’’ and the ‘‘Program Flash’’ shown on the ‘‘Version’’ screenare the same. Files cannot be transferred to the different model anddifferent versions.

Will other files on the PC card likeimages or music files prevent theExport/Import function from working?

No, the system simply adds two small files that are recognized by thenew navigation unit when performing the Import function. However, ifthe PC card is full, the ‘‘Export’’ function won’t work correctly.

Do I have to delete the files on the PCcard after each transfer of thecustomer’s data?

After the transfer of customer data to the new navigation unit, the filesremain on the PC card. Since this is confidential information, werecommend that you delete these files after each use. Please note thateach time you export navigation files of the same model and version, thefiles are overwritten. Over time the PC card will accumulate two files foreach version of the 8 or so Honda navigation models.

What format should be used if the PCcard needs reformatting?

It is unlikely that the PC card will ever need formatting, however the FATfile system should be used.

I can’t enter the navigation diagnosticmode to do the Export/Import function.How can I transfer the customer’sdata?

Some internal navigation unit ECU failures may make it impossible touse the Export/Import function.

Why wont the Export or Importfunctions work?What do I check as part oftroubleshooting?

The card may not be fully inserted into the slot. Eject the PC card, andinspect for warping or damage to the edge connector. Never useexcessive force to insert a PC card. This can result in damage to thepins in the rear of the slot.The PC card may not contain files that are recognized by the newnavigation unit. Navigation data can only be transferred betweennavigation units with the same ‘‘Model code’’, and with the same navi‘‘Program flash’’ version.The flash memory chip type may not be accepted by the system. OnlyCompact Flash, and ATA cards have been tested.The card’s PCMCIA adaptor may be preventing a known-good PC cardfrom playing. Avoid multi slot type PCMCIA adaptors that acceptseveral different flash memory types.The card may be full and as a result the files are stored, but withoutany data. Export and import appear to function, but move nothing.Delete unused files from the PC card.There may not be any files on the PC card. If the card has a ‘‘writeprotection’’ switch, make sure it is turned off before attempting to usethe Export function.Although flash memory chips are reliable, occasionally they developbad sectors or other formatting errors that prevents them fromaccepting files. The PC card should be reformatted using the FATformat.The PC card may have been formatting using the format ‘‘NTFS’’. Onlythe ‘‘FAT’’ format is accepted by the system.Hard Disc Drive (HDD) cards may not work properly in the system andcan overheat or quit functioning, particularly in a hot vehicle. They arenot recommended.Before performing the Import function, ensure that the customer’soriginal DVD is loaded into the new navigation unit and workingproperly.

Model SNCA DownLoad

This screen displays the current version of the program,and allows the loading of a new version of the programeither from a CD/DVD or from a PC card.

The Program Flash version should always be greaterthan or equal to the Program Disc version. IPL, APL,DBOOT, and system uCom are for factory use only.

The Model code is SNC and is for factory use only. Thiscode is stored on a chip in the navigation unit.Therefore, every model has a unique part number forthe navigation unit.

NOTE: If any model number other than SNC isdisplayed, replace the navigation unit with the correctpart. The model code tells the navigation unit whatsoftware to load off the DVD.

Never touch the DownLoad button unless instructed bythe factory. Doing so can overwrite a newer version ofthe software with an older version from the DVD.

In the screen below, touching DownLoad would erasethe newer factory installed flash version (0.99.20) andinstall an older version (0.99.08) from the navigationDVD. This can result in system malfunctions, or createother issues that may inconvenience your customer.
