Circuit/System Description

WARNING: This page is about a different car, the 2017 GMC Acadia Limited, 2017 Chevrolet Traverse, and 2017 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.

AM and FM radio reception is dependent on the following components:

The multi-band antenna is located on the roof of the vehicle. A switched B+ output from the radio entertainment remote enable circuit is used to power the AM/FM portion of this antenna. The antenna enable circuit is also used to control the power state of the amplifier (if equipped) and the rear seat entertainment video display (if equipped).
