MB-Info, general
The MB-Info call function enables the driver 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 following subfunctions:
^ MB-Info call function sequence
^ Function sequence for service center destination entry or points of interest (with code (512) COMAND APS with DVD changer or code (527) COMAND APS with single DVD drive (with navigation))

MB-Info call function sequence
The MB-Info button is read in by the emergency call system control unit via a direct 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 via the following route:
- Direct line
- Multifunction antenna (A28/11)
The MB-Info button's integrated light emitting diode flashes as long as the MB-Info call is activated. This is also indicated in the instrument cluster (A1) and on the Audio/COMAND display (A40/8).
In the event of an MB-Info call, other vehicle-related services with lower priority (e.g. vehicle remote door unlock) are interrupted.
In the event of a multifunction antenna malfunction (e.g. defective because of rollover) the emergency call system control unit automatically uses the emergency call system antenna (A2/52) to transmit mobile phone signals.

Function sequence for service center destination entry or points of interest (with code (512) COMAND APS with DVD changer or code (527) COMAND APS with single DVD drive (with navigation))
During an MB-Info call, for example, the address of a hotel can be loaded into the navigation module in the COMAND controller unit (A40/3).
The service center sends the hotel address by mobile radio signals to the COMAND controller unit via the following route:
- Multifunction antenna
- Direct line
- Emergency call system control unit
- Diagnostic CAN (CAN D)
- Front SAM control unit with fuse and relay module (N10/1)
- Interior CAN (CAN B)
More information on starting the navigation is available in the function description for the Cockpit Management and Data System (COMAND).
The service center destination entry or the point of interest is displayed by the emergency call system control unit in the Audio/ COMAND display via the following route:
- Diagnostic CAN
- Front SAM control unit
- Interior CAN
- COMAND control unit
- Low voltage differential signal (LVDS) line
