Hi, I have a JVC KD-SH707 MP3 Head Unit. It's about 3 yrs old and have never had any problems with it. Until now. I was playing a cd the other day and I switched tracks too far back past 01, it said track 99 and just quit working and ejected the CD. I tried several other CD's and other types of media discs and none of them would read, they would try for about 15 seconds and beep and eject the disc giving a F1 error. Is there anything I can do to solve this problem? A local dealer said they thought it might be the Pick-up eye.
