Hi, I swapped my head unit for an ATOTO A6 and used an aftermarket backup cam retention harness to connect the factory backup cam. Camera works when I'm using accessory power, but when I start the car I get an exclamation point on screen and lose the picture?
Any ideas on why starting the vehicle would change this?
Harness is power, ground, RCA jack for the video and the reverse trigger lead.
It's a 2016 FR-S
