General
The DVD drive of the COMAND controller unit supports playback of video DVDs. 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 playback of video CDs is not supported.

Video mode function sequence
The DVD drive can be used to read out and decode video DVDs. The COMAND controller unit transmits the picture data to the Audio/COMAND display via a low voltage differential signaling (LVDS) line. The "DVD menu" and the "Title menu" are stored on the DVD.

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 output takes place directly over the following speakers:
- 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)

The video image is shown up to a speed of v ≤5 km/h. Only the acoustic playback remains active at speeds of v > 5 km/h. For safety reasons a warning is shown in the Audio/COMAND display.
