I have a z1 thats been working fine till yesterday i was playing a cd and it just stoped playing t tried to press the track back button but accidently pressed the record button. I immediately pressed stop and the cd woulnt play. I pulled out the cd and put it in again and it says unreadable cd. everything i enter is now unreadable cds dvds whatever. I tried turning it off then back on and pressing the reset button but the problem remains. I dont know how because I hardly use the cd part because i have my mp3 player hooked to it and thats how i play all my music. I havent used the cd player in about a month and a half. Is this a software glitch or something that would have to be sent in. if so does anyone no of a repair facilty beside sending it to pioneer.
