Wow, that's a lot of fixing but not much fixed. Hopefully it's finally resolved and lucky there was a factory tech direct from Korea to help troubleshoot it. Please keep us updated for the future.I just got my car back from the dealer yesterday. It was the 4th time I’ve taken it back for the same “ blue screen” camera issue.
The first time - they changed the camera.
The second time - they checked the wiring and connections.
The third time - they changed the AV module.
None of these things fixed my intermittent blue screen issues.
The fourth time (and hopefully the last) they replaced the wiring harness, on the recommendation of a visiting factory tech from Korea.
Hopefully that fixes the problem!
