2010 Chevy Suburban SLT
Radio Screen acts crazy, not every time, seems worse if it's cold outside. It appears to be the screen only, but not the touch function. If you know where to touch the screen, those things work. Usually putting the vehicle in reverse to kick on the backup camera will make it quit acting crazy. Also, the whole screen is delayed when you fire the vehicle up, which is a hassle if you are backing up immediately. I haven't found anything on the internet about this. Already tried disconnecting power, already tried reseating all the plugs. Has anyone else experienced this?

 

I don't know a darn thing about this issue, but I'd unplug the battery; have it tested or test it, then plug it all back in.

Now if you want to know how to program your key-fob, that I could likely help you with.
