Attention:
ALL CD and DVD players should be evaluated for the type of media being used before service or replacement. This bulletin should be posted and all
Service Consultants, Sales Managers and Sales Personnel become familiar with the information contained below. Customers with disc player
concerns covered in this bulletin should be given copies of this information in order to help them understand and maximize the use of the
entertainment system in the vehicle.
Media Types and File Types
A considerable amount of confusion and concerns stem from the types of Media and File types available on a standard (in appearance) Compact Disc for
consumer purchase and/or recording. The information below will address some of this confusion in clear simple terms.
Simple Guidelines to Evaluate CD Concerns:
Whenever you have a concern with Compact Disc skipping, inoperative, sluggish, and/or long search times, you first need to evaluate the system with a
known good disc. ALL GM CD players will accept and play pre-recorded media bearing the Compact Disc logo on the jewel case or the front of the
disc. A diagnostic kit J 39916-CD or J 39916-A is available from Kent-Moore, which includes an evaluation CD to assist you. When testing the system
for the above conditions, never use a customer supplied disc other than for the demonstration of the concern.
^
Even if a customer supplies you with a disc that is "store bought" and appears to be free of scratches and fingerprints, other factors such as long term
exposure to sunlight and/or the heat of the vehicle interior may warp the disc or delaminate the readable surface.
^
Some customers may be using home recorded CD Recordable (CD-R) media in their vehicle. In addition, computer programs that print facsimiles of
original labels on transparent adhesive film may make it difficult to tell a well done CD-R from the original.
^
CD-RW are not readable in any GM CD player and should not be used.
^
Some discs may contain additional features and other non-music data that is unreadable to the CD player.
Important:
In all cases, you should use a known good disc to check proper operation of the CD player.
Load a known good CD into the player or changer. Operate the player and/or drive the vehicle to try to duplicate the customer concern. If the concern
cannot be duplicated with your test CD, refer to the information below to assist you in resolving the customer's concern.
Note:
Advise the customer not to use paste-on labels in GM CD players. The labels may dislodge or curl, damaging or jamming the CD player.
Customer Concerns Related to Home Recorded Discs
Many home computers now come with CD-R/RW drives capable of recording music in standard CD format on a blank disc. A finished CD-R disc is
advertised to work in all CD players. Customers may experience difficulty when using these discs due to several factors:
^
The quality of the finished disc varies with the media used. Off-brand or discount blank discs may have imperfections such that they are not suitable
for automotive applications. A disc that is barely readable may function in a stationary player while skipping in a vehicle due to the vibrations of
driving.
^
The speed at which the disc is recorded will dramatically affect the readability. The laser in the recording drive gets less time to etch the readable
surface of the disc as the recording speed is increased, therefore the data contained on the disc is more faint. A good comparison is if you are trying
