Function requirements for video operation in general
Circuit 30t ON
Transport mode not active
Smartphone not connected over Android Auto (with code 14U (Smartphone Integration Package) or with code 17U (Smartphone Integration Google Automotive Link)) or CarPlay (with code 14U (Smartphone Integration Package) or with code 16U (Smartphone Integration CarPlay)) to the multimedia connection unit or to the front center console USB port.
Video mode, general
The head unit supports the playback of videos on mobile data media and devices (e.g. a USB stick, smartphone) as well as videos (HTML5) from the Internet. The head unit also prepares compressed video data for displaying on the Audio/COMAND display.
Internet usage is described elsewhere.
The mobile data media and devices can be connected via the following components:
Front center console USB port (with code 899 (Multifunction telephony))
USB connector 1 of multimedia connection unit
USB connector 2 of multimedia connection unit
Rear passenger compartment multimedia connection (model 290 with code 531 (COMAND APS))
The video function can be operated using the:
Upper control panel control unit
Right lower control panel
Audio/COMAND control panel (except code 446 (Touchpad only))
Touchpad (with code 446 (Touchpad only) or with code 448 (Touchpad))
Head unit multifunction steering wheel button group
Function sequence for video mode
The menu for the media sources can be called up the upper control panel control unit.
The control signals are sent via the following route:
LCP LIN
Audio/COMAND control panel (except code 446 (Touchpad only)) or Touchpad (with code 446 (Touchpad only))
Telematics CAN
Head unit
The media source can be activated with the Audio/COMAND control panel (except code 446 (Touchpad only)) or with the touchpad (with code 446 (Touchpad only) or with code 448 (Touchpad)). The Audio/COMAND control panel and the touchpad transmit the control signals via the telematics CAN to the head unit.
The video functions can be operated using the head unit multifunction steering wheel button group. The control signals of the head unit multifunction steering wheel button group are forwarded via the following route:
Steering wheel electronics
Steering wheel CAN
Steering column tube module control unit
Suspension FlexRay
Electronic ignition lock control unit
User interface CAN
Head unit
The head unit receives the audio and video signals over an USB (Universal Serial Bus) connection from the multimedia connection unit, front center console USB port (with code 899 (Multifunction telephony)) or from the rear passenger compartment multimedia connection (model 290 with code 531 (COMAND APS)). The head unit processes the video signals and transmits them via an HSVL line to the Audio/COMAND display.
The audio signals are sent by the head unit to the following components:
Speaker system (model 257 (except 257.361) except code 810 (Sound system) and except code 811 (Advanced Sound System))
Midline sound system amplifier control unit, over MOST (model 257.361, model 290 except code 810 (Sound system) and except code 811 (Advanced Sound System))
Sound system amplifier control unit, over MOST (with code 810 (Sound system))
Advanced Sound System amplifier control unit, over MOST (with code 811 (Advanced Sound System))
The volume can be adjusted using the volume control button on the right lower control panel.
On model 257, the volume control button operation signal is forwarded over the following route:
LCP LIN
Audio/COMAND control panel (except code 446 (Touchpad only)) or Touchpad (with code 446 (Touchpad only))
Telematics CAN
Head unit
On model 290, the volume control button operation signal is forwarded over the following route:
Drive Unit CAN
Drive Unit control unit
LCP LIN
Audio/COMAND control panel (except code 446 (Touchpad only)) or Touchpad (with code 446 (Touchpad only))
Telematics CAN
Head unit
The volume can be adjusted using the head unit multifunction steering wheel button group. The control signals of the head unit multifunction steering wheel button group are forwarded via the following route:
Steering wheel electronics
Steering wheel CAN
Steering column tube module control unit
Suspension FlexRay
Electronic ignition lock control unit
User interface CAN
