Note:
For Information Only

If you receive customer reports in the above model vehicles having one or all of the conditions listed below, please ensure a navigation DVD is inserted in the navigation processor (navigation DVD drive in trunk) at all times before releasing the vehicle to the field.

^ Audio system switches OFF for a few seconds approximately every 2-3 minutes

^ Some of the speakers emit no sound

^ Telematics system shuts down completely and then re-starts

When the DVD is not detected by the navigation processor, as a result, the navigation processor will perform an internal reset causing the COMAND head unit to switch OFF at regular time intervals.
