- with CODE (359) TELE AID emergency call system

Function requirements
^ Circuit 30
^ Emergency call system authorized and operating properly
^ The vehicle-related MB-Info call service is separately authorized
^ An emergency call system control unit (N123/4) communication module authorized for the vehicle-related MBInfo call service is configured ex-factory with the telephone number of the corresponding service provider
^ The customer is registered and authorized at the service center
^ One mobile phone network is available in sufficient strength and quality
^ Triggering an MB-Info call by pressing the MB-Info button (S93/6s1) > 0.5 s
^ A higher-priority vehicle-related service is not active

Depending on the equipment installed, one of the following control units will be installed, hereafter referred to as the "audio unit":
- Radio (A2), with code (510) Audio 20 including CD changer
- COMAND operating, display and controller unit (A40/3), with code (512) COMAND APS with DVD changer

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), with code (512) COMAND APS including DVD changer

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 via 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
- Left antenna amplifier module (A2/64)
- Direct line
- Rod antenna (A28)

As long as the MB-Info call is active, the light emitting diode (LED) integrated into the MB-Info button flashes. This is also indicated in the instrument cluster (A1) and on the display of the "audio unit".

In the event of an MB-Info call, other vehicle-related services (e.g. vehicle remote door unlock) are interrupted.

In the event of a failure of the rod antenna (defective e.g. due to rollover), the emergency call system control unit for transferring the mobile phone signals and data transmits and receives the mobile phone signals and data in the following way:
- Direct line
- Emergency call system antenna splitter (A2/25)
- Direct line
- Emergency call system left backup antenna (A2/54)
- Emergency call system right backup antenna (A2/55)

Function sequence for Remote Destination Feed or Points of Interest (POI), with code (512) COMAND APS including DVD changer
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 sends the address of the hotel by means of mobile phone signals or data to the emergency call system control unit in the following way:
- Rod antenna
- Direct line
- Left antenna amplifier module
- 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
