U1128 - Loss of Communications with IRC
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.

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