Antenna system, radio (4D): Antennas
The antennas for radio reception are integrated in the rear window and are located as follows:
- AM - antenna positioned at the top of the rear window.
- FM - antenna (antennae) integrated in the heating element.
The rear window is the same on all markets.
The antenna signal is amplified by an amplifier located on the right-hand C-pillar. The Premium and Prestige systems have one of two different antenna amplifiers, red or black, depending on the market. The black amplifier is used for the Popular system.
The antenna amplifier is supplied with trigger voltage from pin 14 (K16A) on the head unit and is grounded by being bolted to the chassis.
The black amplifier is used on all markets for retrofitted radios.
The left-hand C-pillar has an antenna filter that grounds the heating element but prevents the antenna signal from going to ground. The antenna filter is fitted as standard on all cars.
