TV Antenna Module (If Equipped)
WARNING: This page is about a different car, the 2009 Cadillac STS. However, it is still accessible from the selected car via links, so may be relevant.
The TV antenna module is used by the navigation radio to automatically select the antenna combination that provides the strongest TV signal to the navigation radio. The TV antenna module also provides the vehicle information communication system (VICS) FM signal to the VICS card (export, w/UE9).
