Hey guys the other morning I made a couple of stops and after one stop when I got back in the truck and started it up I had no Nav. or radio. Just a black screen and it wasn't working. It wouldn't turn on so I checked the fuses for the amp/radio and misc ign. I also cycled the door locks and set the alarm and disarmed it stilll no radio/nav. After I checked the fuses I got back in the truck it was working (it went into self healing mode). I thought the screen flashed once during the day but, I couldn't be sure, I was going from under a ramp into the sun with sunglasses on so I think it was just my eyes. It's been working ever since. Any thoughts? Thanks. Eric.

You can check for DTCs but don't know if you will get any radio/amp codes without a Tech 2, this will be hard to diagnose when it's working right now.

When it was into the dealer for my rear parking assist not working they said there wasn't any codes for the radio. Eric
