PC card will not play/card icon on audio

Unfortunately there are no error messages, and no
diagnostics for the PC card. There are many reasons
why 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 the
edge connector. N ever use excessive force to insert a
card. This can result in damage to the pins in the rear
of the slot.
 The client’s card may contain audio files that are not recognized by the system. Only MP3, and WMA
music files are played.
 The flash card type may not be accepted by the system. Only Compact Flash and ATA cards have
been tested.
 The card’s PCMCIA adaptor may be preventing a known-good card from playing. New PCMCIA
adaptors are constantly being released, and have not
been tested.
 The card’s capacity may exceed 1 GB. Only cards with capacities of up to 1 GB (1000 MB) have been
tested.
 There may not be any files on the card. Some cards have write protection, make sure it is turned off
before putting files on the card.
 Although flash memory chips are reliable, occasionally they develop bad sectors or other
formatting errors that prevents them from playing.
The customer should re-format the card using the
FAT, or FAT32 format.  The card may have been damaged by heat. Suggest
that the client remove their card when exiting the
vehicle.
 The client may have formatted the card using the format NTFS. Only the formats FAT, and FAT32 are
accepted by the system.
 Hard Disc Drive (HDD) cards may not work properly in the system and can overheat and quit functioning,
particularly in a hot vehicle. They are not
recommended.
 The filing structure of the card may exceed the specification of 8 folder levels deep, 99 folders
maximum, and 999 total tracks maximum. If any of
these limitations is exceeded, the system may not
properly display or play the tracks.
NOTE: A delay when first inserting a card is normal.
The system is reading the File Tag information for
album names, artist, and song titles and there is no
hour glass, The delay length depends on the number of
tracks, and the complexity of the folder structure.
See the audio section glossary for an explanation of the
terms used above.

NOTE: Check the vehicle battery condition first.
 Make sure that the correct DVD color and version are installed.
 Check any official Honda service website for more service information about the navigation system.
 Check the connector for poor connection or loose terminals.
 Before troubleshooting, make sure you have the navigation system 4-digit anti-theft code.
 After troubleshooting, enter the navigation system anti-theft code.
Before assuming that a voice complaint is hardware
related, ensure that the voice control system is being
operated correctly.  Make sure you are on the correct screen when trying to issue a voice command. For instance, the
command ‘‘Find the nearest Italian Restaurant’’ only
works on a Map screen (See the Navigation System
Manual for a complete list of allowed voice
commands for the information being displayed.).
 Close the windows, moonroof, and doors.
 Set the fan speed to low (1 or 2).
 Adjust the air flow from the air conditioning vents so that they do not blow against the microphone on the
ceiling.
 Pause after pressing the navigation TALK button, then give a voice command clearly in a natural
speaking voice. If the system cannot recognize your
command, speak louder.
 If the microphone picks up voices other than yours, the system may not interpret your voice commands
correctly.
 If you speak a command with something in your mouth, or your voice is too husky, the system may
misunderstand your command.
 Compare the system operation with a known-good vehicle. Have more than one person test the system
operation. If the known-good vehicle performs the
same, it is a characteristic of the system. 1. Turn the ignition switch to ON (II).
2. Go into the Diagnostic Menu and use the Mic Level
test under Functional Setup (see page 23-147) to
check the operation of the navigation TALK and
navigation BACK buttons.
Go to step 10.
Go to step 3.
3. Turn the ignition switch to LOCK (0).
4. Do the voice control switch test (see page 23-156).
Go to step 5.
Replace the voice control switch.
5. Disconnect the cable reel 20P connector and navigation unit connector D (5P).
6. Check for continuity between body ground and navigation unit connector D (5P) terminal No. 4.
Repair short to body ground in the wire
between the navigation unit and the voice control
switch, or replace the cable reel.
Go to step 7.

 Check any official Honda service website for more service information about the navigation system.
 Check the Navigation System Manual for a list of common DVD screen error messages and the
probable cause.
 Go into the Diagnostic Menu, and use the Car Status test (see page 23-141) to check the status of the
display.
1. Check the DVD-ROM reading surface for scratches.
Replace the DVD-ROM.
If the problem occurs occasionally when the
system is cold, this is normal. If the problem occurs
frequently when driving, replace the navigation
unit (see page 23-155). 1. When a navigation unit is powered up for the first
time at the factory, the factory diagnosis screen (In
Line Diag) appears. Normally the factory performs
the steps necessary to verify proper operation and
terminate the factory diagnostic. Until the proper
confirmation sequence is performed, the screen
will appear every time the vehicle is started.
2. Follow the steps to prevent the screen from showingupinthefuture:
 Hold down the buttons (Menu, Map/Guide, and Cancel) for about 5 seconds (the Select Diagnosis
Items screen appears).
 Hold down the Map/Guide button for 5 10 seconds (A screen with a Complete button
appears).
 Touch Complete, and then the Return button (the system may re-boot).
 Restart the vehicle, and confirm normal operation by completing the PDI of the
navigation system Service Bulletin.

1. Remove the key from the ignition.
Go to step 2.
The system is OK at this time.
2. The vehicle may have been used as a demonstration vehicle at an event like an auto
show. In these events, power is often jumpered to
the navigation system so that the ignition key is not
needed in the vehicle. At the end of the show, the
jumper wire may not have been removed. Check
the navigation unit connector A (17P) for a non-
factory jumper wire in series with the factory cable.
Remove the jumper wire, and re-test. Return
the jumper wire to Tech Line.
Go to step 3.
