Frontview Camera
WARNING: This page is about a different car, the 2018 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.
The system uses a Frontview Camera mounted to the inside rearview mirror. The Performance Data Recorder provides the Frontview Camera battery voltage and ground and receives audio and video signals from the Frontview Camera via a discreet USB harness.
