Location
The radio is centrally located in the instrument panel.
Tasks
- Central control unit for the entertainment and communication systems integrated into the vehicle
- Integration of smartphones (model 166 as of 14.12.2015, model 292 as of 01.12.2015)
- Reading in of input signals as well as actuation of output media and system components
Central control unit for the entertainment and communication systems integrated into the vehicle
The radio provides the user with a structured and standard user interface for the following system components:
- Audio system (e.g. "Radio", "CD" (as well as MP3) and further multimedia devices)
- Telephony (with telephone book function)
- Internet
- - sound settings (e.g. "bass", "treble", "fader", "balance")
- System settings (e.g. "Brightness" and "Contrast" of the Audio/COMAND display (A40/8))
- Navigation (with CODE 522 (Audio 20 radio) and CODE 357 (SD card navigation))
The user interface is shown on the Audio/COMAND display. Using the "Vehicle functions" menu, equipment-dependent contents and functions of additional systems (e.g. climate control, seat adjustments) can be shown and controlled on the Audio/COMAND display.
MODEL 166 as of model year 2016 with CODE 357 (Map navigation) with CODE 522 (Audio 20 radio)
MODEL 292 with CODE 357 (Map navigation) with CODE 522 (Audio 20 radio)
The navigation functions can be used via a voice control system integrated in the navigation system.
Integration of smartphones (model 166 as of 14.12.2015, model 292 as of 01.12.2015)
The radio enables the integration of smartphones. In order to ensure that the content is prepared in a vehicle-related way, only apps that have been developed for the following integration standards are supported:
- Automotive Link (Google)
- CarPlay (Apple)
- MirrorLink 1.1 (Car Connectivity Consortium)
To be able to use the smartphone applications, the smartphone has to be connected to the multimedia connection unit (A90/5) using the Universal Serial Bus (USB), and the integration standard selected using a radio menu. If a smartphone is connected and an integration standard is activated, the radio is set to a special operating mode ("Integration mode"), in which the radio's media player, telephony and navigation cannot be used. The "radio", "vehicle settings" and safety relevant functions, such as emergency call function (with CODE 348 (Emergency call/assist system) or with CODE 350 (Ecall Europe emergency call system)), can still be used.
When in integration mode, the radio supports the smartphone applications as follows:
- Forwarding of control signals (e.g. from Audio/COMAND control panel (A40/9), from + and - button, setting for specific functions and volume control (S111s1), from the Accept/terminate phone call button (S111s3))
- Forwarding of signals from the hands-free system microphone group (A67b1) (e.g. for voice control or telephony)
- Audio outputs (e.g. for voice-operated control or telephony) over the speaker system or forwarding of signals to the sound system amplifier control unit (N40/3) (with CODE 810 (Sound system))
- Muting of radio reception, e.g. for smartphone telephony
- Forwarding of position data (e.g. GPS signals, gyro sensor signals, wheel speed signals)
- Forwarding of generated video signals from the smartphone to the Audio/COMAND display
No smartphone applications are shown in the instrument cluster (A1).
If the smartphone is being used to make a call, the audio equipment receives and transmits the telephone signals from and to the smartphone using Automotive Link and MirrorLink 1.1 via the Bluetooth® antenna (A2/91), and with CarPlay via the USB connection to the multimedia connection unit.
Reading in of input signals as well as actuation of output media and system components
The radio sends and receives signals via the following connections:
- CAN
- Media Oriented System Transport (MOST)
- Ethernet
- Direct line
CAN
The radio is a subscriber of the telematics CAN (CAN A) and the interior CAN (CAN B):
- The telematics CAN is used by the radio, e.g. to receive the control signals from the Audio/COMAND control panel.
- Via the telematics CAN, the radio sends control signals to the Audio/COMAND display for example
- The radio receives, e.g. the signals of the left multifunction steering wheel button group (S110) and the right multifunction steering wheel button group (S111) over the interior CAN from the instrument cluster.
- The radio uses the interior CAN, e g. to send navigation displays (with CODE 357 (SD card navigation)) to the instrument cluster.
Media Oriented System Transport (MOST)
The radio exchanges data with the following control units over MOST:
- Sound system amplifier control unit (with CODE 810 (Sound system))
- Tuner unit (A90/4) (with CODE 536 (SIRIUS satellite radio) or with CODE 537 (Digital radio (DAB)))
Ethernet
The radio is connected to the diagnostic connector (X11/4) via the Ethernet.
