General
The MB-Info call function enables the customer to call up information on Mercedes-Benz brand products as well as further voice-based services (e.g. hotel booking).
This vehicle-related service is primarily an oral information service that is provided via the communications module integrated into the emergency call system control unit.
The MB-Info function consists of the two following subfunctions:
^ MB-Info call function sequence
^ Function sequence for remote destination feed or points of interest (POI)

MB-Info call function sequence
The MB-Info button is read in by the emergency call system control unit over a discrete line. The emergency call system control unit then completes a voice connection to the service center. After the service center replies with a special tone, the emergency call system control unit automatically sends an SMS with the following data to the service center over the integrated communication module:
- Vehicle position
- Customer identification data
- Vehicle identification data

The communication module integrated into the emergency call system control unit transmits and receives the mobile phone signals or data in the following way:
- Direct line
- Frequency switchover control unit (N96), with code (389) Mobile phone preinstallation with universal interface, USA/ Canada, and direct line
- Telephone antenna (A2/22)

As long as the MB-Info call is active, the light emitting diode (LED) integrated into the MB-Info button flashes. This is also displayed in the instrument cluster (A1) and on the display on the COMAND operating, display and controller unit (A40/3).

In the event of an MB-Info call, other vehicle-related services (e.g. vehicle remote door unlock) and, for vehicles with code (389) Mobile phone preinstallation with universal interface, USA/Canada, any active mobile phone connections are interrupted.

In the event of failure of the telephone antenna (e.g. defective due to rollover), the emergency call system control unit automatically uses the TELE AID backup antenna (A2/50) to transmit the mobile phone signals or data.

Function sequence for remote destination feed or points of interest (POI)
During an MB-Info call, for example, the address of a hotel can be loaded into the navigation module in the COMAND operating, display and controller unit.
The service center transmits the address of the hotel by means of mobile phone signals or data to the emergency call system control unit over the following path:
- Telephone antenna
- Direct line
- Frequency switchover control unit, with code (389) Mobile phone preinstallation with universal interface, USA/Canada, and direct line

The customer confirms receipt of the hotel address and can then start the navigation.

Detailed information on starting the navigation is given in the specific system description for the COMAND display, operating, display and controller unit.

The displays for Remote Destination Feed or Points of Interest (POI) are shown by the emergency call control unit on the display of the COMAND operating, display and controller unit over the following path:
- Diagnostic CAN
- Central gateway control unit (N93)
- Interior CAN
- COMAND operating, display and controller unit
