Audio Module (AUM) (2001-2007): Design: Antenna
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2007 Volvo V70, 2006 Volvo V70, 2005 Volvo V70, 2004 Volvo V70, and 2003 Volvo V70. However, it is still accessible from the selected car via links, so may be relevant.
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.
