I just have the base sync with 4 inch screen. I went to the store and shut off the truck while the radio was playing and sat there for a bit. I opened the door which shut off the radio and went in to the store. When I came back out to the truck and started it, the 4 inch screen nor the radio would play. Just a blank screen. The USB port has power and my instrument panel is working fine. What might be the issue? I have cut the truck off and on a few times and no change. Next step is to disconnect the battery. Figured I would ask if anyone has experienced this before.

 

Drove for a bit and cut it off. Came back to my truck 20 minutes later and it works. Any reason this would happen?
