My cd is displaying 00000A0 what does it mean

Try disconnecting the car battery for 5 mins

sounds like the laser has gone bad

This unit needs a service visit. It may be a common problem with that model but to me it sound like a power supply issue as when you play a disc more power is used to rotate motors and move the sled. This is indicating to you that it is in a weakened condition and will soon fail more significantly. The problem may be as little as a solder joint or a defective Filter capacitor which is common in some models of equipment.

Hello
If a disc has been put in the slot of the disc in play, Remove the disc, whose number is displayed, and press stop button.
Because of light or noise, the changer has detected a disc in the lot of the disc being played, even though it is empty. Check whether there is a disc in the displayed slot. With front panel closed, hold down "STOP " button for atl least four seconds or more.

the lens is not good it can't read the cd

either the player cannot play the cd (usually happens with computer copied cd's) or you should try any kind of original audio cd that is not copied form a computer and if the problem persist, then take the radio to get checked while it;s still under warranty.

you can down load/veiw the manual at pioneerusa.com, you neeed to search for the model in the search bar for manuals, there is also a 1800 number for pioneeer you can call

archo69..big chance your laser is on its way out..it also can be the bottom lense is dirty to ,but this requires your stereo to be removed .dismantled and cleaned manually

We have the same problem and are searching all over the web for a solution but no luck. If we find a solution we will come back and post what we found. :)

According to the manual, error 11 means the disc is inserted upside down.
