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). For example, it provides information on the following services:
^ Current traffic conditions
^ Technical questions, complaints and services
^ Mercedes-Benz products and Mercedes Card
^ Leasing and financial offers

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 call function consists of the two following subfunctions:
^ MB-Info call function sequence
^ Function sequence for display of additional services

MB-Info call function sequence
The MB-Info button is read in directly by the emergency call system control unit via a discrete line.
The emergency call system control unit automatically transmits an SMS with the following data via the integrated communication module to the CAC:
^ Vehicle position
^ Customer identification data
^ Vehicle identification data

Additionally, the communication module integrated into the emergency call system control unit sets up a voice communication to the CAC.

The communication module integrated into the emergency call system control unit transmits and receives the mobile phone signals or data in the following way:
^ Discrete line
^ Frequency switchover control unit (N96), with code (389) Mobile phone preinstallation with universal interface, USA/ Canada
^ Discrete line
^ Multifunction antenna (A28/11)

The MB-Info button's integrated light emitting diode (LED) flashes as long as the MB-Info call is activated.

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 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 or data.

Function sequence for display of additional services
Also available are the following services which are shown on the Audio/COMAND display (A40/8):
^ Destination Feed In (transmission of destinations which can then be actuated using the navigation system), with code (512) COMAND APS with DVD changer
^ Freetext (transmission of text messages)

The other services, e.g. Freetext (transmission of text messages), are sent to the Audio/COMAND display by the emergency call system control unit in the following way:
^ Diagnostic CAN
^ Front SAM control unit with fuse and relay module (N10/1)
^ Interior CAN
^ "Master control unit"
^ Low Voltage Differential Signaling (LVDS) line
