Why is my radio screen still on when car is off?
The most common cause of this problem is an improperly wired head unit, so if you have an aftermarket radio, that’s the first place to look.
Why is my radio not turning on?
The most likely reason for your radio’s sudden death is a blown fuse. All car radios have at least one fuse that protects it from power surges coming from somewhere else in the vehicle. The first thing you should do when your radio stops working is check its fuses and replace any that have blown.
How do I reset my car radio?
Turn your car on, but do not start the engine. Turn the radio off. Hold the radio power button down for a few minutes until it resets.
