I get this code does anyone have any info. I have a aftermarket headunit that a local stereo shop installed they said they used the new metra box with a downloaded update. Also the sound dims out when i satrt the car and put it in reverse or if a message comes up on the dic (like low range or tpms)

Please help stereo shop has no clue anymore.

Sounds like they tapped into something they shouldn't have if you didn't have this issue before, or used the wrong metra kit.
