Location

The Audio/COMAND display is fitted to the top center of the instrument panel.

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.

Moreover, the Audio/COMAND display makes possible the presentation of two different views at the same time. This function enables the driver and front passenger to access video picture information or vehicle system information at the same time and independently from one another (dual viewing mode).

Due to the design of the Audio/COMAND display, the visual range of the driver (1) and visual range of the front passenger (2) are defined in a fixed manner and an insufficient picture quality is possible in the overlap area (3) of the visual ranges.

The front passenger can operate the Audio/COMAND display using the remote control (A8/7) (the signals are read in by the COMAND controller unit (A40/3)). A uniform picture can be output via a mono output mode.

The Audio/COMAND display receives the following signals:

Circuit 30g and circuit 31
Control signals (e.g. switch on) via the telematics CAN (CAN A) from the COMAND controller unit
Picture signals via the low voltage differential signal (LVDS) interface from the COMAND controller unit
Audio signals via the telematics CAN from the COMAND controller unit

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

The Audio/COMAND display sends the following signals:

Audio signals via a direct line to the headphones (cabled) electrical connector (X39/6)

Body

The Audio/COMAND display is an 8" Thin Film Transistor (TFT) color SPLITVIEW display in 16:9 format with a resolution of 800 X480 pixels.

In order to prevent damage to the Audio/COMAND display, it is protected by a tinted acrylic glass lens.

It is not possible to swivel the Audio/COMAND display.

The dual viewing mode may be deactivated at the factory as the function is not yet legally allowed in all regions. The activation can be performed by the dealer, however, if it conforms to the law.

Function

Brightness is controlled internally in the Audio/COMAND display using the integrated light sensor. In order to prevent overheating of the Audio/COMAND display, it is cooled by an internal blower motor. Cooling is controlled internally in the Audio/COMAND display using the integrated temperature sensor. The temperature of the Audio/COMAND display is kept below 85 °C during operation and below 95 °C with the vehicle at a standstill.
