Block diagram of COMAND TV system
The marked elements are the components which are essentially used for TV mode.
NOTE: The COMAND TV system (optional) is presently still in preparation (status 3/99).
On/Off Behavior, Function
Switch-on behavior
Activation of navigation
When the driver's door is opened the navigation feature is automatically activated via CAN bus (A1-A40/3). This procedure requires approx. 2 s and
may be accompanied by weak audible noises from the CD-ROM drive integrated into the navigation processor. The display on the COMAND operating,
display arid control module (A40/3) remains switched off.
When the status of the ignition switch then does not change (e.g. circuit 15C or 15R ON) the navigation feature remains activated for 30 minutes.
Activation of entire system
When the ignition switch is turned to the approx. 20 ° position (c. 15C ON) all other subsystems are activated, in position 1 (c. 15R ON) the display is
switched on if the COMAND module was switched on before the ignition key was removed previously. The COMAND system is then ready for
operation. The system active before it was last switched off (e.g. radio) is switched on and the corresponding basic menu displayed. If the COMAND
feature was switched off for longer than 30 minutes, a warning menu appears with general information on the use of the system.
Effect of pressing "ON" button
COMAND can also be switched on by pressing the "ON" button even when the remote control key (A8/1) is not inserted. All COMAND functions are
then available for 30 minutes. After expiration of 30 minutes, the COMAND system automatically switches off.
The system can be switched on again by pressing the "ON" button, when it has switched off after 30 minutes. The 30 minutes cycle then starts again
from the beginning.
Switch-off behavior
The COMAND system is switched off when the ignition key is removed (C. 15C OFF). The 30 minutes shut-off delay ("stand-by operation") for the
navigation system then starts. During this time, all important location finding parameters remain stored.
