Antenna: Description and Operation

Antenna System

The antenna system consists of a rear window antenna system for the radio reception with diversity as well as a roof antenna (RX5) for the cellular phone and navigation system. USA and Canada vehicles also have an optional antenna for satellite radio reception integrated inside the roof antenna.

For the rear window antenna, positive and negative frequency filters are installed.

The antenna system with diversity function serves to improve and optimize the reception quality in the vehicle.

The diversity functions are directly integrated in the radio or radio/navigation system unit; there is no additional control module for antenna selection in the vehicle.

• Before troubleshooting or servicing, the technicians must be familiar with the function and operation of the radio system.

• Additional information may be found in the Owner's Manual.

• When the battery is connected, check the all the vehicle accessories (radio, clock, electronic conveniences, etc.) according to the repair information and/or the Owner's Manual.

For servicing or fault finding, use Vehicle Diagnostic Tester in "Guided Fault Finding" and.
