So I'm new here so hello everyone. This has probably been BTD, but I'll reach out anyway. I purchased a used '14 Silverado LT Z71. No factory installed BU Camera. I purchased the camera and installed myself. I am a supervisory equipment mechanic by trade for 34 years. It was a very simple install, 30 minutes tops. The truck has an I04 option code on the tag so the camera should of been plug and play with a flash at a local dealer. Took it to the dealer and they cant make the camera work. I had the key fobs programmed as well. Almost $500 later, and the camera still doesn't work. They claim they could not get the flash to work even after talking to GM Tech. I'm at a loss and don't want to spend any more money on "troubleshooting" if it is a hardware issue.
