I have a 120 gb iPod classic. It is about a year old. I had my iPod plugged into my car yesterday and it made some weird noises like the song was skipping. I shut it off and turned it back on and went to a different song and it was fine. But whenever I change the volume it makes those same skipping noises or whenever I have a song playing and I try to go to a different menu or something. Pretty much whenever I use the click wheel it makes those noises. Is there anything I can do to fix it?
