• No smartphone is connected via the Android Auto or CarPlay standard.

Video mode 

The head unit supports playback of videos, including compressed video data, from the Internet. The video image is shown on the Audio/COMAND display. The head unit is responsible for the required processing of the video data for displaying the images on the Audio/COMAND display.

The Internet browser is not able to play back flash videos.

The video mode function can be operated using the:

• Lower control panel at the right (volume control) or upper control panel control unit (menu) 

  The lower control panel at the right and the upper control panel control unit send the operation signals over the LCP-LIN, Audio/COMAND control panel and the telematics CAN to the head unit.

• Audio/COMAND control panel 

  The Audio/COMAND control panel sends the control signals via telematics CAN to the head unit.

• Touchpad 

  The touchpad sends the operation signals over the telematics CAN to the head unit.

• Head unit multifunction steering wheel button group 

  The steering wheel electronics reads the control signals directly. The steering column tube module control unit reads them in over the steering-wheel CAN and sends them to the head unit over the suspension FlexRay, electronic ignition lock control unit and the user interface CAN.

The head unit reads in the video data and sends the processed data for display over the HSVL line to the Audio/COMAND display.

Audio is output depending on the equipment variant:

• For vehicles except code EU8 (Burmester 3D Surround Sound System) the head unit actuates the audio output over the speaker system.
• For vehicles with EU8 (Burmester 3D Surround Sound System), the head unit sends the audio signals over MOST to the sound system amplifier control unit. The sound system amplifier control unit amplifies these and outputs the audio via the speaker system.
