Volvo: radio antenna, antenna amplifier, rear windshield

Question
I have a 1999 S80. My AM stations are terrible. Where is the antenna?

Answer
Vito,
The FM waveband uses a diversity system consisting of two antennas. One of the diversity system antennas is integrated in the rear windshield heating loops, the other is in the rear bumper.
Only cars with factory-installed radios have an antenna amplifier for the diversity system. After market accessory radios may require installation of an after market accessory antenna amplifier for the diversity system for interference free FM reception.
If tinted film is applied to the rear windshield, check the antenna wires for damage and adhesion.
You may wish to call your local dealer as there is a factory bulletin about antennas.
