Function
The buttons on the operating panel of the COMAND controller unit are read in and relayed to the central computer. The signals from the button
operations are processed further in the central computer and forwarded via the telematics CAN or the interior CAN to the other system components in
the form of messages. If the ON button on the COMAND controller unit is pressed, the COMAND controller unit is switched on. The volume for the
respective set audio source is regulated by turning the rotary switch. The function keys switch over to the audio source desired by the user.
These additional functions are also available:
DVD drive
An audio/video CD/DVD can be played using the integrated DVD drive.
Navigation and global positioning system (GPS) control unit
The navigation processor is integrated into the COMAND controller unit and calculates the location of the vehicle using the incoming antenna signals. It
also calculates the vehicle's route after the destination has been entered.
Turn rate sensor
The turn rate sensor determines the direction changes of the vehicle. It is installed into the navigation processor. A calibration is not required.
Diagnosis
The COMAND controller unit is the diagnosis gateway. The diagnostic communication takes place between the COMAND controller unit and the front
SAM control unit with fuse and relay module (N10/1) via the interior CAN. The diagnostic communication between the front SAM control unit with fuse
and relay module and the diagnostic connector (X11/4) connected to Star Diagnosis is performed via the diagnostic CAN (CAN D).
