GF82.60-P-3200R SDAR Control Unit, Component Description

GF82.60-P-3200R SDAR Control Unit, Component Description
- with CODE (536) SIRIUS satellite radio

Component Identification:

Location
The SDAR control unit is located on the wheelhouse on the left of the trunk

Task
The signals received by the SDAR antenna (A2/82) are decoded by the SDAR control unit and sent to the COMAND operating, display and controller unit (A40/3).

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

Discrete inputs
^ Circuit 30
^ Circuit 31
^ "Wake-Up" signal
^ SDAR antenna signals

Up to 31.5.05 signals were transferred from the SDAR antenna to the SDAR control unit over 2 antenna lines. As of 1.6.05 this is modified to one antenna line.

Discrete outputs
^ Voltage supply for SDAR antenna

Digital data bus (D2B) (up to 31.5.04)
^ Exchange of control and data signals

Media Oriented System Transport (MOST) (as of 1.6.04)
^ Exchange of control and data signals
