Navigation Radios May Not Play MP3s - keywords CD disc display inoperative U3U

This PI was superseded to update MP3 functionality. Please discard PIC4471.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Some customers may comment that their Navigation radio will not play MP3's. Typically this concern will occur when the customer creates several folders and burns the disc as a DATA DISC. Data disc's can be made in two different formats. These formats are refered to as Mode 1 or Mode 2/XA. Format Mode 1 is selectable only through the software program that the customer used to burn the CD. Some software may not allow this Mode to be selected. It has been found that typically, if the software used to burn the CD does not allow the user to select Mode 1, then the software is likely burning the CD in Mode 2/XA.

Important: Mode 2/XA is NOT supported by the Navigation Radio.

If you are unable to select Mode 1 prior to burning the disc, you should contact the software manufacturer for assistance. Many software programs that support selection of Mode 1 also allow you to view the Disc Properties which may also indicate what Mode the customer's CD was burned in. The customer may have to purchase additional software at their own expense in order to burn CDs that will be compatible with the Navigation Radio and comply with the required criteria as covered in the Owner's Manual.

This is normal operation of the Navigation Radio. Do not replace the radio for this concern. Additional information that referenced MP3 formats can be found in the customer's owners manual or Navigation Radio Supplement.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
