^ The Cockpit Management and Data System (COMAND) is authorized and working correctly.

General information on video DVD
The DVD drive of the COMAND controller unit supports playback of video DVDs. Here, the video image is shown on the Audio/ COMAND display (A40/8) once the "VIDEO" menu and then the "DVD" submenu have been activated.
The system can be operated using the:
^ Audio/COMAND control panel (A40/9)
^ Control fields on the COMAND controller unit

Function sequence
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.

Audio output of the amplified and processed signals takes place via discrete lines through 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)

On model designation 204.0 with code (810) Sound system, the right rear surround speaker is integrated into the bass speaker (H4/29).

On model designation 204.2 with code (810) Sound system, the left rear surround speaker (H4/54) is installed in the left D-pillar and the right rear surround speaker (H4/57) in the right D-pillar. The bass speaker (H4/29) is installed in the left load compartment.

On vehicles except code (810) Sound system, the audio output takes place directly over discrete lines via the COMAND controller unit through the following speakers:
^ Left front door speaker
^ Right front door speaker
^ Left rear door speaker
^ Right rear door speaker
^ Center instrument panel speaker

The DVD/CD video function is only available when the vehicle is stationary (up to 3 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.
