Circuit/System Description

WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.

The surround vision camera system has an X20 Card Reader Receptacle located in the luggage compartment. The X20 Card Reader Receptacle interfaces with the K157 Video Processing Control Module via a USB cable. The X20 Card Reader Receptacle also receives fused battery voltage and ground from the K157 Video Processing Control Module. The K157 Video Processing Control Module uses the memory card as a mass storage device, similar to a USB storage device.
