Mute button wont turn off

Unfortunately, this unit does not have a cell phone mute feature, so you will not be able to do it using the deck. You will have to look into an external solution.

There should be a button labeled ATT that is your mute button. Att is short for attenuation.

The yellow wire with the black stripe is for connecting a phone. That allows the phone to mute the radio in the event of a call. It is not necessary to hook that up unless your phone has that option. And im pretty sure your phone has BT.

It happened to me today and it passed after a while when i was arriving home. Try to reset it by taking the power source off for a couple of minutes then try again.
Don't forget about your system definitions, it will be restored to default.

why has my pioneer saying mute

Sounds maybe like you may have gotten something sticky by the buttons maybe its just physically **** not broken. Try Mr. Clean dilutted of course to unstick and clean the unit.

hi there
to fix this press and hold the source button till unit turns off the source button switches from CD - radio...................once your unit powers off........press and hold the function button down till the clock appears in display you should also hear a beep when this happens.........press the function button repeatedly until the telephone feature appears now switch by pressing the skip button to ATT (Attention) once this is done press the source button to power on the pioneer unit simply turn up the volume and problem should be solved......
hope i was able to help

You have to isolate yellow-black cabel. This cabel was in contact with earth and it was the reason, why you have Mute on the display.

you have to turn the headunit off using the headunit (there is a button that says off or power just cant remember which one) once its off and is displaying only the time you hold the function button and all the other options will come up.

Make sure the unit is turned off. Then press and hold the function button for about 3-5 seconds. It should beep and the clock should be displayed. Then press up or down then left or right.
