The satellite radio system enables digital satellite stations to be received. The system consists of the SDAR control unit and the associated SDAR antenna (A2/93a5), which is integrated into the roof antenna module. The SDAR control unit is connected to the COMAND operating, display and controller unit via MOST.

IMPORTANT The SDAR control unit (3rd generation) has been used since modification year 07/1, and now it is also available for vehicles with code (460) Additional parts, Canadian vehicles. The SDAR control unit (3rd generation) differs from the previous generation on account of the following properties:

For this purpose, the audio signals are transferred by the COMAND, operating, display and controller unit to the rear audio control unit over direct wiring. There, the signals are amplified and output directly to the HBF control unit for output to the headphones.

Making phone calls 

The cell phone (A34/6) is inserted into the UPCI [UHI] (Universal Portable CTEL Interface) cell phone holder (A34/15) and is thereby connected to the Universal Portable CTEL Interface (UPCI [UHI]) control unit. The telephone feature is included in the UPCI (Universal portable CTEL Interface) control unit. The user can operate the system with the COMAND, operating, display and controller unit. The Universal Portable CTEL Interface (UPCI [UHI]) control unit is connected to the COMAND operating, display and controller unit via MOST.
