    I have the same problem, except not with CDs. It happens when I plug in my iPhone, it will play the song but says ERROR A0 and I can't control anything, not even change bass or sub controls which one person suggested is the problem.

    Same problem here. I unplugged and let the unit sit for 24 hours. Then I plugged back in and CD ejected. Unfortunately as soon as I inserted another, I got the same message.

Ok so I just fixed my problem. Although I was getting the error because of using an iPhone instead of a CD I believe it is the same solution.

As jjgomex suggested it was pulling to much power, to what I did was turn on the headunit switch the source to something other than what causes the problem.

Then go to the Audio settings in the menu and turn bass all the way down and Sub Control to -1.

Then turn off headunit and turn it on again and switch to the source of problem, it should be fixed, or at least it did for me.

:) Good Luck!

I had this problem in my pioneer car radio with symptoms similar to those above. My solution was to reset the

  1. Turn off all heaters, fans, lights.
  2. Take off the NEGATIVE ( - ) Battery terminal, turn ON the headlights (this will drain whatever power left in the line)
  3. Turn OFF the headlights (DONT FORGET) and Reconnect the terminal,
  4. KEY in ignition, radio has power but might not light up...quickly press eject to get the cd out. Now press power on your radio to turn it on and it should be fine (CD should play also)

Same porblem I thought it was a problem with the power. It seems when my sub woofer is pulling too much power I recieve ERROR-AO. The only way to eject with out dissasembleing it is to turn off the car so no power and eject as soon as you turn the car back on. let me know if there is a way to fix the problem.

My pioneer car stereo DEH-P77MP won't play cd's anymore. the radio still works, but on the screen it says cd error AO or A0. i was wondering what problem this code relates to? hope you can help,...

This is a common error with these units when they get dusty from putting dirty disks inside the drive. Just go to your local staples and or walmart and get a 5 dollar disk player cleaning kit. It looks like a plain cd but has small fibers that come out of the bottom of the disc that clean the laser as it spins and tries to read it.

Need help installing DEH-P7500MP in 79 chevy truck. Do you have any solutions?

The best way is to get an installation kit. It comes with the surround to put the new stereo in, and install where the stock stereo was. It also has a wiring harness in connect your new stereo, and a plug that will plug into the factory radio plugs.

A0 error canyou fix it?

If you really enjoy the head unit call pioneer, there customer service is great and before you fork out another $300 for a new unit why not hear what they have to offer. Some companies have refurbed units ready to ship, just an option.

PIONEER DEH-P7500MP is there a way to do a master reset as the stereo will not let me download new pictures or movie screens

CLICK HERE for your user manual

There is a small hole just big enough for a paperclip on the face of the radio (when the faceplate is removed)
Press and hold for at least 3 seconds.

Alternately, disconnect the power wire for 10 minutes.

This might be casued by dust and dirt on the lens. If you can get the top off and get at the laser then a small paintbrush would clean it up nicely.
