^ Reads in the controls and input signals
^ Evaluation of input factors
^ Actuates output media

Central control and display device for entertainment and communications systems integrated into vehicle
The radio provides the user with a structured and uniform interface.

Reads in the controls and input signals
The input factors are read in via the following connections:
^ Direct line
^ Controller Area Network (data bus/CAN bus) (CAN)
^ Media Oriented System Transport (MOST)

Discrete input signals
- Circuit 30
- Circuit 31
- Telephone MUTE
- Left antenna amplifier module (A2/64)
- Bluetooth antenna (A2/91)
- Hands-free system microphone group (B25)
- AUX input (accessible in glove compartment), except code (518) Media interface

CAN
The radio is an interior CAN subscriber. It communicates with the following components, for example:
- Instrument cluster (A1)
- EIS [EZS] control unit (N73)
- Steering column tube module (N80)

MOST
Control and audio signals from the following control units:
- Media interface control unit (N125/1), with code (518) Media interface

Function
The buttons for the control panel on the radio are read in and made available to the integrated central computer. The button actuations are processed further in the central computer and transferred to other system components as a messages via the MOST or interior CAN. The radio is switched On or Off when the On/Off button on the radio is pressed. The volume is regulated by turning the volume setting button for each set audio source. Pressing the function keys enables the user to switch to the desired system components.

CD-6-disk changer
The integrated CD changer can be used to play audio CDs (including in MP3 format).
