Audio System

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. Never 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 client 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.
