I just picked up a 2013 express double cab that came with a RA1 radio. The first thing I did was upgrade to a RA2 that came out of a 2015 truck and added the mirror/harness/steering wheel controls to get Bluetooth voice calls. I had the dealer flash the XAC code when I brought the truck in to get the radio unlocked because I knew the next thing I would do is add a backup camera. After I had the code flashed, there was no blue screen when the truck was put in reverse and no camera options in the safety/assist menu, only hill start assist.
Now I have wired up the 82214240 camera kit but still nothing shows on the display in reverse and no menu options for the camera. I took the truck back to the dealer for them to confirm the XAC code was flashed. I also purchased AlfaOBD to verify the rear view camera is enabled.
I have double checked the wiring of the camera harness, but I assume the issue is within the radio/bcm? From browsing the forum I understand I should be seeing at least a blue screen in reverse with the XAC code flashed, even with no camera installed. Is that correct? Is there a specific software version I need to add to the radio if the donor truck did not have a camera?
