GRAND AM COMPACT DISC PLAYER (MINI DISC PLAYER)

Models Affected: 1989 GRAND AM

In January 1988, manufacturers of compact discs released a new format for compact discs. The new discs are 70mm in diameter, compared to the standard 120mm. Since the 1989 Pontiac Grand AM has no provisions to play the 70mm discs, it may be necessary to advise customers of the conditions they will encounter if they try to use the new 'mini' discs.

"MINI" DISC WITHOUT ADAPTER:

If a "mini" disc is inserted in the slot without an adapter, the player will load the disc. The disc will be loaded too far into the mechanism and the hole in the disc will not be aligned with the spindle and therefore, the loading sequence can't be completed. When the user tries to eject the disc, the edge may get caught under the disc clamp and jam. The player must then be removed from the car and sent to a radio repair shop to have the disc removed.

"MINI" DISC WITH ADAPTER:

Several adapter designs have been introduced. Some of the adapter designs have clips which can get caught in the loading mechanism. When this happens, the disc player must be removed from the car and sent to a radio repair shop. Other adapter designs may allow the disc to partially eject and then reload the disc. When this happens, it is usually possible to remove the disc by allowing it to play for a short time (2 seconds minimum) and ejecting it again.

NOTICE: Informational warnnings have been included in the owner's manual the service manual, and on a tag on the front of the radio.
