The navigation processor continuously calculates the location of the vehicle with the aid of the following
procedures:
GPS location finding
Basic location finding (dead reckoning)
Map-supported location finding (map matching)
The correct position is determined by continuously comparing the locating result of these three procedures.
Route calculation
The route is calculated in the navigation processor according to the destination entered, or automatically, after
deviating from the recommended route. The recommended route is stored in the navigation processor
Guidance
After the navigation processor has calculated the route, guidance is started. The driver receives continuous
information with the aid of guidance symbols appearing on the display of the radio and navigation unit
(A2/56) and voice announcements on the vehicle loudspeaker.

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.
