Why is my stereo working but no sound?
Silent stereos are usually caused by low power, a wrong source selection, disconnected or faulty speaker wires, broken speakers, or a malfunctioning source component.
Why did my dual radio stop working?
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 dual stereo?
Press the RESET button to reset the unit back to the factory settings if abnormal operation occurs. The reset button is located behind the front panel. With the unit on, press and hold DISP until the clock begins to flash, then release.
