Question about Pioneer DEH-P4100
Check none of the buttons are stuck in. Try pressing the reset button. I think it is bottom right and recessed in a hole. The unit should be on and you'll need something pointy like a pen or toothpick. If you cant find the reset button, disconnect the car battery for a minute or two. If that doen't work, then it will probably need repair.
