OK, I spoke to Pioneer tech support and they had me go to destination>settings>connection status. If the parking brake shows "off", many of the functions will not work as a safety measure. I guess this is their version of interlock. I think it can be defeated with a wire-around, but thats what they say the problem is.

SOURCE: Volume Button on steering wheel not responsive!

There is a metal dome under each button, some time they became warped or inverted and you don't get the actuating contact on the first push but if you keep on pressing it eventually contact will be made and whoalaa actuation happened. If you are technical incline you can replace it with a dome of similar size of a device you no longer have use for, like a remote control, an old car stereo or telephone...ect. Goodluck.

My pioneer avh-p5000 wont unmute. I have already pulled the faceplate off and reset it by pressing the reset button and when I turned it back on it was still muted. It doesent matter what source it is on....

  • Hello and thank you for the opportunity to assist you.

  • Are you getting any errors numbers? Any special icons on the screen? Cables hooked up properly?

  • Have you tried just turning the volume up to see if the mute removes itself? I know you press the knob to mute it but turn the volume up to increase the volume.

  • When you reset the radio did you follow these steps exactlly?

  1. Ignition off first.
  2. Then remove the front panel.
  3. Now engine on.
  4. Now press and hold the reset button for 5 seconds.
  • If your steps were different try this first. If they were the same then you need to reset the entire unit not just the processor.

  • To do a master reset the unit must loose power for a couple minutes. In other words unhook the power or remove both battery cables for two minutes and try it again. Make sure to have any codes you need handy before doing this procedure.

  • Let me know how you do with these steps. If it takes care of you please do rate and comment.

the guy that wrote how to unlock the receiver left the most important parts out... guess dint wanna be helpful...

Bypass code for radio that our locked

Thank you for your e-mail. Put in the same number 3 times (example 1111) until it locks and then push in the mute bottom and hold it and while you hold the mute button with your other finger push in the volume control (power button) and hold both of them until a new screen comes up and then put in 122164 and hit OK and that should work.

let me break it down you do not need the remote...

first put the same number in (e.g 1111 enter this number 3 times) second after the device locks on the radio hold the mute button while holding that press in the volume nob (e.g power button) hold them both till another screen comes up and enter 122164 and press ok and your all done... this solution works on all dual indash dvd players
