I don't have PDC or camera so I can't answer. I had a strange issue though. I installed the CIC and used it for several weeks before coding. The donor vehicle had PDC, so when i shifted into reverse I got a blank screen with the PDC icon in corner. After coding, when ever I would shift into reverse the CIC would reboot, very annoying. For weeks I thought I had coded wrong. I recoded the CIC for PDC even though my car didn't have the sensors and the rebooting stopped. I considered installing the rear camera, but gave up when I read about the problem w/factory camera and retrofit emulator. I have't searched to see if anyone has a simple fix.
