The DVD video 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 (A40/8).

Video mode, general
The DVD drive of the COMAND controller unit (A40/3) supports playback of video DVDs. A DVD changer is integrated into the COMAND controller unit with code (512) COMAND APS incl. DVD changer or with code (528) COMAND incl. DVD changer and a single DVD drive is installed with code (527) COMAND APS with single DVD drive (with navigation). The video image is shown in the Audio/COMAND display 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 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 dashboard speaker (H4/27)
- Left rear surround speaker (H4/54)
- Right rear surround speaker (H4/55) (with model 212.2)
- Right rear surround speaker (H4/57) (with model 212.0)
- 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 and bass speakers (H4/72)
- Right front door sound system midrange and bass speakers (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) (model 212.0) or for the bass speaker (H4/29) (model 212.2), the audio signal is routed from the COMAND controller unit to the sound system amplifier control unit via MOST and from there to the bass speaker via the rear bass speaker amplifier (N40/9) using direct lines.

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)
