PC CARD WILL NOT PLAY/CARD ICON ON AUDIO SCREEN CANNOT BE SELECTED (WITH
NAVIGATION)

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 customer'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 adapter may be preventing a known-good card from
playing. New PCMCIA adapters 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 prevent them from playing. The
customer should reformat the card using the FAT or FAT32 format.
