To unmute your Pioneer car stereo:
Press and hold the source button until the stereo turns off. Press and hold the function button until the Device beeps.
The most likely cause of sudden death on your radio is a blown fuse. All car stereos have at least one fuse that protects them from power surges coming from somewhere else in the vehicle. The first thing to do when your radio stops working is to check the fuses and replace any that have blown.
If your radio turns on but there is no sound. First check the radio functions, make sure you have selected an audio source such as radio. If you are using AUX, USB or BT AUDIO, make sure you have connected a device to the correct input. Make sure the radio is not muted.
To do this, you must turn your ignition ON. Turn on your radio and see if it displays CODE or LOC. If this is the case, turn off the radio. Press and hold the audio on/off button along with the SEEK button for about 50-60 minutes.
