Reason for change
Complaint:
Intermittently no audio output, regardless of the selected audio source. When the "Sirius" satellite radio is selected, the message "Device
Unavailable" appears in the central display.
The fault is usually rectified after an ignition cycle.
Cause:
Software release 11/07 00 of Sirius satellite radio control unit with a HW number of A171 870 XX XX.
Remedy:
Software update of "Sirius" satellite radio to the software release 08/49 00.
This is done by means of control unit programming using Xentry Diagnostics in the "SDAR - Satellite Digital Audio Radio (N87/5)" control unit
under the Adaptations tab.

To install the software, Xentry Diagnostics version 11/2012 or higher must be installed on the Star Diagnosis unit and used with:
