Antenna
The audio module (AUM) has an antenna system for AM and FM. This consists partly of an AM antenna and partly of a dual antenna system for FM
(Diversity reception). The dual antenna system is used to reduce Multipath interference. One antenna is integrated in the rear windshield (left-hand rear
side window V70/V70XC). The other antenna is integrated in the rear bumper. The signals from the antennae are amplified or adjusted by each
individual antenna amplifier.
