GF82.60-P-0006QOU Satellite Radio (SDAR), Function
- with CODE (536) SIRIUS satellite radio

Following activation of the COMAND operating, display and controller unit (A40/3) (with code (530) COMAND APS USA (with navigation system)) or the radio (A2) by pressing the "ON" button and when the "SAT" menu has been selected, SDAR antenna (A2/82) (up to 31.5.06) or SDAR antenna (A2/49a4) (as of 1.6.06) receives S-band satellite signals. SDAR antenna (A2/82) or SDAR antenna (A2/49a4) is able to receive the corresponding signals even from terrestrial fill-in transmitters (usually in cities). The satellite signals received by SDAR antenna (A2/82) or SDAR antenna (A2/49a4) are forwarded over a coaxial cable to SDAR control unit (N87/5). However, the "Satellite radio" function must be enabled by a network operator to permit reception. When operated for the first time, the "SAT" menu displays the telephone number and the identification of the network operator on the screen.

Satellite receivers are characterized by a high number of storable stations in order to be able to cope with the wealth of available stations. If the "satellite radio" function has been enabled, between 100 and 224 stations can be additionally received. Station display and selection is performed on the radio (A2) or with code (530) COMAND APS USA (with navigation system) using the COMAND operating, display and controller unit (A40/3).
The S-band satellite signals are forwarded to the SDAR control unit (N87/5), where they are processed and then transmitted over Media Oriented System Transport (MOST) to the radio (A2) or with code (530) COMAND APS USA (with navigation system) to the COMAND operating, display and controller unit (A40/3).

Since modification year 07/1 the SDAR control unit (N87/5) (3rd generation) has been used, which is now also available for vehicles with code (460) Additional parts, Canadian vehicles. The SDAR control unit (N87/5) (3rd generation) differs from previous generations through the following features:
^ Shorter response times
^ Improved reception properties
^ Temperature and electromagnetic compatibility (EMC) properties have been optimized
