Additional telematics services in general

The telematics services of the emergency call system are realized via a mobile radio connection to the Service Center. The telematics services communications module transmits and receives the mobile phone signals via the emergency call system antenna (A2/52).

In addition to the emergency call, the following services are possible:

Towing service ("Accident Management")
Breakdown assistance ("Breakdown Management")
Service and maintenance ("Maintenance and Teleguard")
App services ("Online and Remote") (with CODE 531 (COMAND APS))

The real-time traffic data service (with CODE B54 (Live Traffic Information)) is described in the document "Navigation mode, function".

With all services, vehicle data is transmitted to the Service Center. The services towing service, breakdown assistance and some service and maintenance functions can be used when the customer selects the telephone book entry "MB Contact" via the audio equipment. The telematics services communications module establishes a voice connection to the Service Center via the emergency call system antenna and transmits vehicle data. The telematics services communications module receives the request for establishing a voice connection from the audio equipment via the following route:

Interior CAN
Electronic ignition switch control unit
Diagnostic CAN

With the service and maintenance service, if there is no customer contract for service and maintenance a pop-up window is displayed in the vehicle on the Audio/COMAND display (A40/8) 5 days before a calculated service is due, via which the system asks whether a connection to the Customer Center should be established. If the customer selects "Call now", a voice connection is established to the Service Center. If the customer selects "Call later", the pop-up window is displayed again later. If the customer selects "No, thank you", no pop-up window is displayed when the service is due. The telematics services communications module forwards the data for displaying the pop-up window to the audio equipment via the following route:

Diagnostic CAN
Electronic ignition switch control unit
Interior CAN

The audio equipment transmits the picture signals via a LVDS line (Low Voltage Differential Signal) to the Audio/COMAND display. With the service and maintenance with customer contract service and the App services (with CODE 531 (COMAND APS)), contact between the customer and the Service Center is established independently of the vehicle (e.g. via the Internet or via the mobile phone) and the Service Center queries vehicle data or transmits control signals to the vehicle.

App services are e.g. transferring the vehicle location ("Vehicle Finder"), transmitting the vehicle location, as soon as the vehicle has reached or leaves a certain area ("Vehicle Tracker/Geofencing"), remote door unlocking and locking ("Remote Lock/Unlock"), display of the vehicle status ("Remote Status").

The telematics services communications module receives the vehicle data via the diagnostic CAN (CAN D) from the electronic ignition lock control unit (N73) and sends received operation requests via the diagnostic CAN to the electronic ignition lock control unit.
