Antenna Diversity Module with Amplifier
The high frequency signals broadcast by the radio stations are received via the rear
window antennas (FM1, FM2, FM3 and AM)
The antenna amplifiers are in the antenna diversity module. There are separate amplifiers
for AM and FM. The antenna amplifier (of the antenna diversity module) is located
between the 3rd brake light and roof antenna.
When the CIC is switched on, the antenna diversity/amplifier is activated and powered by
the Rad_On signal. The remote control service part of the antenna diversity module is
powered via terminal 30.
The high frequency signals from the AM and FM antennas as well as from the is
amplified. These signals are routed via a ribbon cable from the rear window to the anten-
na diversity module.
The antennal amplifier also supports the frequencies of the weatherband.
Weatherband is transmitted over seven channels in the frequency range from 162.400
MHz to 162.550 MHz. The weatherband tuner is incorporated in the FM module of the
head unit.
