General information 

The TV mode enables the vehicle to pick up television channels on the Japanese National Television System Committee (NTSC) frequency range and to view them on the Audio/COMAND display (A40/8). The interface is generated and displayed by the COMAND controller unit.

IMPORTANT The TV picture is switched off as from a speed of 5 km/h. When the vehicle is moving, only acoustic playback remains active and - for safety reasons - a warning is shown on the Audio/COMAND display.

TV mode function sequence 

The antenna signals for TV reception are received by the following amplifiers:

The received antenna signals are sent via a discrete line to the TV tuner control unit (N143) and then forwarded via a discrete line to the COMAND controller unit. The COMAND controller unit sends the antenna signals via a low voltage differential signal (LVDS) line to the Audio/COMAND display. The audio signals are transmitted by the COMAND controller unit in vehicles with code (810) Sound system to the sound system amplifier control unit (N40/3) over the Media Oriented System Transport (MOST).

From there, the audio signals are transmitted via discrete lines to the following speakers:

IMPORTANT In vehicles except code (810) Sound system, the audio output takes place directly from the COMAND controller unit via discrete lines to the following speakers:
