My first problem concerns my command center and touch screen which is unresponsive to touch. Before it didnt react to touch, then it worked for a while. Now its completely unresponsive. All the physical buttons next to the screen is working. I tried turning on/off but still same.

my second fault is my rear reverse camera. It worked before when in Reverse, but now command center is black with no signal Message. I did some electrical work near rear SAM in trunk( just to troubleshoot my low CAN voltages in OBD port) Which Cable runs from reverse camera to SAM? Sounds like a loose connection I must accidently touched but I cant figure which.
These two faults are not linked to each other. Because touch screen worked before when reverse cam showed no signal.
