Function sequence for video mode
The video signals are transmitted via a separate video line to the COMAND controller unit. The COMAND controller unit transmits the picture data to the Audio/COMAND display via a low voltage differential signal (LVDS) line.
The audio signals on vehicles with code (810) Sound system, are sent over the Media Oriented System Transport (MOST) to the sound system amplifier control unit (N40/3) where they are amplified and then processed to match the stored tone settings.
The audio is output by the following speakers via direct lines:
- Center instrument panel speaker (H4/27)
- Left rear surround speaker (H4/54)
- Right rear surround speaker (H4/57)
- Left front door sound system bass speaker (H4/64)
- Right front door sound system bass speaker (H4/65)
- Left front door sound system tweeter (H4/68)
- Right front door sound system tweeter (H4/69)
- Left rear door sound system tweeter (H4/70)
- Right rear door sound system tweeter (H4/71)
- Left front door sound system midrange speaker (H4/72)
- Right front door sound system midrange speaker (H4/73)
- Left rear door sound system midrange speaker (H4/80)
- Right rear door sound system midrange speaker (H4/81)
For the bass speaker (H4/17), the audio signal is routed via MOST from the COMAND controller unit to the sound system amplifier control unit and from there via direct lines to the bass speaker via the rear bass speaker amplifier (N40/9).
On vehicles without code (810) Sound system, the audio signals are output over direct lines by the COMAND controller unit to the following speakers:
- Left front door speaker (H4/1)
- Left front door tweeter (H4/1h1)
- Right front door speaker (H4/2)
- Right front door tweeter (H4/2h1)
- Left rear door speaker (H4/3)
- Left rear door tweeter (H4/3h1)
- Right rear door speaker (H4/4)
- Right rear door tweeter (H4/4h1)
The video DVD function is only available when the vehicle is stationary (v < 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.
