This was almost my problem, close but no cigar. However, you guys got me thinking that I should pull out my OEM deck and have a look at the wires.
My backup camera has started fading to black way to often and I missed the 3 year/60,000 kms secret/hidden warranty. I have less than 57,000 kms as of writing this post on my 2018. I am the original owner and the car is 100% stock. According to the dealer, the OEM head unit is failing and I need a replacement.
They tried a software update but that didn't work. I highly doubt they pulled the head unit out to look at it. Now I'm hoping for a lose wire connection on the backup camera.
