GF82.62-P-3122RI Right Antenna Amplifier Module Component Description

Component Identification:

Location
The right antenna amplifier module is mounted on the front roof frame above the glove box.

Task
The right antenna amplifier module receives the signals from antennas 3 and 4 in the windshield and forwards them. In detail, the right antenna amplifier module has the following tasks:
^ Receiving, amplifying and forwarding FM2 radio signals
^ Receiving, amplifying and forwarding of TV signals, with code (863) Digital/analog TV tuner or code (865) TV tuner
^ Receiving and forwarding radio remote central locking (RRCL [FZV]) signals
^ Other inputs

Receiving, amplifying and forwarding FM2 radio signals
The FM2 radio signals from the antennas in the windshield are received via a direct line, filtered, amplified and then forwarded via another direct line to the COMAND operating, display and controller unit (A40/3).

Receiving, amplifying and forwarding of TV signals, with code (863) Digital/analog TV tuner or code (865) TV tuner
The TV signals from the antennas in the windshield are received via 2 direct lines, amplified, filtered and then forwarded via another 2 direct lines to the TV combination tuner (analog/digital) (A90/1) (with code (863) Digital/analog TV tuner) or the TV digital tuner (A90/3) (with code (865) TV tuner).

Receiving and forwarding radio remote central locking (RRCL [FZV]) signals
The windshield antenna receives the signals of the transmitter key (A8/1), which are forwarded via a direct line to the right antenna amplifier module. The signals are digitized and forwarded via a direct line to the overhead control panel control unit (N70) and from there to the electronic ignition switch control unit (N73) for checking the drive authorization code.

Other inputs
- Power supply, circuit 30 via a direct line
