This happened to me once. I pulled the fuse for the radio for about 30 seconds (can't remember the fuse number, looked it up in the book), it cycled through CD's again, and about a minute later started working.Earlier I was doing some work on my car where I had to disconnect my battery, I didn't think it was gonna be that long but it was disconnected for about 20 min. I had 5 cd's in my stock Radio. When I re-connected the battery the cd player was making noises, kinda like moving thru cd's. Later when I Drove the car the cd player didn't wanna work, when I press mode only SAT shows, no cd player?? Can someone please explain what happened. It's the stock 6 disc mp3 player. Hopefully it ain't broke and maybe there's a re-connect procedure for it.
