System concept of information service:
The vehicle owner determines his own interest profile for service information such as world news or stock
exchange data. He transmits the desired information to the Mercedes Benz Customer Service. This profile is
indicated to the S ervice O peration Center (SOC ).
With the" SVC " button on the radio and navigation module (A2/56) it is possible to transmit an update
request for service information to the S ervice O perating C enter (SOC ).
In the S ervice O peration C enter (SOC ) this customer profile is used for selecting information. The desired
information is compiled by the information provider and transmitted to the vehicle via the S ervice O peration C
enter (SOC ).
The data transmitted is indicated on the display in the radio and navigation module (A2/56) .

A GSM cellular telephone can be connected by means of a coaxial cable to the non-designated
connection.
The CTEL and GPS antenna splitter (A2/57) consists of the following components:
Active frequency splitter with GPS antenna amplifier
Coaxial socket for the CTEL and GPS roof antenna (A2/49)
Coaxial socket for a GSM CTEL
Coaxial socket for a GPS receiver
The voltage for the CTEL and GPS antenna splitter (A2/57) is supplied via the coaxial cable from the
GPS receiver ( phantom feed ).
ANTENNA SPLITTER, FUNCTION - GF82.85-P-3107-04B
Model 163 with code 353
The CTEL and GPS antenna splitter (A2/57) has the following functions:
Separating the signals received from the CTEL and GPS roof antenna (A2/49) :
The GSM and GPS signals are received by the antenna splitter via an antenna lead and leave the CTEL
and GPS antenna splitter (A2/57) via two separate coaxial cables. In addition the GPS signals are
amplified.
Decoupling the GPS receiver from the GSM telephone transmitter:
It must be ensured that the telephone transmitter signals do not reach the GPS receiver. The CTEL and
GPS antenna splitter (A2/57) allows them to pass only in the direction of the roof antenna.

The CTEL and GPS antenna splitter (A2/57)has the following functions:
Separating the receiving signals from the CTEL and GPS roof antenna (A2/49) :
The GSM and the GPS signals are received along an antenna cable at the antenna splitter and leave the
CTEL and GPS antenna splitter (A2/57) in two separate coaxial cables. The GPS signals are
additionally amplified.
Decoupling the GPS receiver from the transmitter of the GSM cellular telephone:
The transmission signals of the cellular telephone must not reach the GPS receiver. They are passed
through by the CTEL and GPS antenna splitter (A2/57) only in the direction of the roof antenna.
