(Component Description For Audio/COMAND® Display - GF54.30-P-6150GR)
MODEL 166
up to model year 2016
Shown on model 166.0
Location
The Audio/COMAND® display is fitted to the top center of the instrument panel.
Tasks
The Audio/COMAND® display serves the uniform depiction of user-relevant navigation, control and information windows as well as the depiction for video, TV and Internet applications, if present on the vehicle.
Audio/COMAND® display with CODE 867 (SPLITVIEW)
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). The operation of the Audio/COMAND® display for the front passenger occurs using a remote control (the signals are read in by the COMAND® controller unit (A40/3)). A uniform picture can be output via a mono output 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. 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. The temperature of the Audio/COMAND® display is kept below 85°C during operation and below 95°C with the vehicle at a standstill.
The Audio/COMAND® display also has the following tasks:
- Reading in of signals
- Evaluation of input factors
Reading in of signals
The input factors are read in and displayed via the following connections:
- Telematics CAN (CAN A)
- Low voltage differential signal (LVDS) connection
Telematics CAN
The Audio/COMAND® display receives control signals (e.g. brightness, on or off display) over the telematics CAN.
Low voltage differential signal (LVDS) connection
The Audio/COMAND® display receives all the information for displaying appropriate content from the audio equipment, with CODE 867 (SPLITVIEW) from the COMAND® controller unit over the LVDS interface.
Evaluation of input factors
The input factors are evaluated by the integrated microprocessor and the relevant components are then actuated internally.
Design
Audio/COMAND® display with CODE 867 (SPLITVIEW)
The Audio/COMAND® display is an 8 - Thin Film Transistor (TFT) color SPLITVIEW display in a 16:9 with a resolution of 800X480 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.
