Tasks 

The Audio/COMAND® display serves the uniform presentation of user-relevant operating and information windows as well as the presentation of video picture information.

The Audio/COMAND® display receives the following signals:

• Control signals (e.g. switch on) over the telematics CAN (CAN A) from the head unit (A26/17)
• Picture signals via the low voltage differential signaling (LVDS) interface (Model 205 up to Model year 2019, Model 253 (except for 253.99) up to Model year 2020) or via the high speed video link (HSVL) interface (Model 205 as of Model year 2019, Model 253.99, Model 253 (except 253.99) as of Model year 2020) from the head unit

The Audio/COMAND® display evaluates the input factors in the integrated microprocessor, and actuates the color screen.

Model 253 (except 253.99) as of Model year 2020: The Audio/COMAND® display detects swipe movements and touch movements on the display and transmits the operation signals to the head unit via the telematics CAN.
