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.
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:
- TV 1 antenna amplifier and DAB Band III (A94/1)
- TV 2 antenna amplifier and KEYLESS GO (A94/2)
- TV 3 antenna amplifier (A94/3)
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:
- Left front door speaker (H4/1)
- Right front door speaker (H4/2)
- Left rear door speaker (H4/3)
- Right rear door speaker (H4/4)
- Center instrument panel speaker (H4/27)
- Bass speaker (H4/29)
- Left rear surround speaker (H4/54)
- Right rear surround speaker (H4/57)
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:
- Left front door speaker
- Right front door speaker
- Left rear door speaker
- Right rear door speaker
- Center instrument panel speaker
