CTEL and GPS roof antenna (A2/49)
The CTEL and GPS roof antenna (A2/49) is a combination antenna for the telephone and GPS.
The integrated GPS antenna (A2/49a2) receives the GPS satellite signals. This antenna does not transmit
signals.
The integrated CTEL antenna (A2/49a1) receives and transmits GSM radio signals.
The CTEL and GPS radio signals are transmitted to an antenna socket used by both. For this reason only one
antenna cable is required.
The CTEL and GPS roof antenna (A2/49) is an active antenna. It is supplied with DC power via the antenna
cable (phantom feed). The electronic circuitry in the antenna must ensure that
the telephone transmitter signals are only transmitted to the CTEL antenna (A2/49a1) .
the signals received by both antennas are available at an antenna output.
The antenna is connected to the CTEL and GPS antenna splitter (A2/57) by a coaxial cable.

Function up to 31.8.01
The GPS/CTEL roof antenna (A2/49) is a combination antenna for telephone and GPS.
The CTEL and GPS roof antenna (A2/49) receives the GPS satellite signals. No GPS signals are transmitted
over this range of the antenna.
The CTEL and GPS roof antenna (A2/49) receives and transmits the GSM radio signals.
The radio signals for CTEL and GPS are transmitted to the CTEL and GPS antenna splitter (A2/57) via a
common antenna cable.
The CTEL and GPS roof antenna (A2/49) is an active antenna .
It is supplied with direct voltage via the antenna cable ( phantom feed ). The electronics in the antenna must
ensure that the
transmission signals of the cellular telephone are transmitted by the CTEL and GPS roof antenna
(A2/49)
the received signals of both antennas are made available to an antenna output.
The antenna is linked via a coaxial cable to the CTEL and GPS antenna splitter (A2/57) .
Function as of 01.09.01
The CTEL and GPS roof antenna (A2/49) is a new version of the combination antenna for CTEL and GPS.
It has an integrated antenna splitter and an antenna amplifier, which eliminates the need for the CTEL and
GPS antenna splitter (A2/57) . splitter
The CTEL and GPS roof antenna (A2/49) has connections for

Fig. 83: MCS System Block Diagram
MCS system
The radio and navigation unit (A2/56) is the central component of the MCS system . It has a video-capable 5"
active matrix TFT display for indicating information such as control menus and map data for navigation.
Actuation is accomplished in operating modes NTSC (US standard) PAL (ECE standard). It is operated with
fixed function keys and a rotary knob, a joystick as well as with menu-guidance on the display.
The basic version of the radio and navigation unit (A2/56) is equipped with
a radio reception unit,
a compact cassette player and
a speed-dependent volume control.
Diagnostic interface
To read out actual values and DTC's of the MCS and components connected via the digital data bus ( D2B )
diagnosis with the hand-held tester is possible via a K-line.

The digital components of the radio and navigation unit (A2/56)are interlinked via the digital data bus
( D2B ). Control data, audio signals and other information are transmitted between the various system
components via the digital data bus ( D2B ) Since some of the individual components operate with various data
formats or place different requirements on the transmission speed and transmission security, various bus
systems are installed.
