Circuit/System Description

WARNING: This page is about a different car, the 2018 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 applique. One of the antenna amplifiers will receive either both AM, FM, and DAB signals, while the other antenna amplifier receives FM2 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 center conductor of the antenna coaxial cable. When a 12 V signal is seen by the antenna amplifiers on the remote enable circuit, the AM, FM, DAB, and FM2 signals are amplified.
