I have a 2017 Blackout edition (w/t) regular cab that came with IOB and factory backup camera which I bought brand new. My factory carplay stopped working so I upgraded to a Stinger Heigh10. Unfortunately, we have not been able to make the factory backup camera work. The screen switches to backup camera when in reverse but I get no video signal. Because this truck came with IOB there is no HMI behind the glove box to connect the camera harness to. I've also seen in the schematics on gmupfitter that there is an HMI bypass module on the driver side above the BCM. I've looked there as well with no luck. Any other ideas on where I might be able to find the video feed from the factory backup camera?
Greatly appreciate any help.
Thanks!
