I have had my terrain a little over a year. Just within the last month the radio would shut off randomly, the screen buttons wouldn’t work/or steering wheel controls. I checked the fuses and replaced anyways, checked the wires for exposure but didn’t see any problems. Yesterday my radio completely crapped out. It will not turn on at all, no back up camera, audio etc. the controls for heat/air work fine. I can’t seem to find anything posting on what exactly the problem is with the radio other than LOTS of people seem to be having a similar problem. Any ideas?
