Circuit/System Description

WARNING: This page is about a different car, the 2015 Chevrolet Camaro. However, it is still accessible from the selected car via links, so may be relevant.

Active Antenna (U77)

The active antenna system uses an integral antenna applied as an appliqu e to the rear glass. The antenna module receives both AM and FM signals from the rear glass antenna. The radio antenna module is enabled when the radio is turned on. The radio provides battery voltage to the antenna module using the center conductor of the antenna coaxial cable. When a 12 V signal is seen by the module on the center conductor of the antenna coax, both AM and FM signals are amplified.

Spoiler Antenna (UB3)

The radio antenna is integral to the spoiler on the rear decklid. The antenna module on the underside of the spoiler receives both AM and FM signals from the antenna. The radio antenna module is enabled when the radio is turned on. The radio provides battery voltage to the antenna module using the remote enable circuit. When a 12 V signal is seen by the antenna module on the remote enable circuit, both AM and FM signals are amplified.
