I've got what I believe is the same problem as Brian55. When trying to play a song the counter stays at 0:00 and the progress bar does not advance. I've had an ipod with a sound jack problem and this is different. with a sound jack problem you can look at the ipod and tell the song is playing because the progress bar and counter are progressing but no sound is coming out. With this unit the song just never actually starts. I've ruled out the hard drive and click wheel as problems by switching them out with known good parts. any suggestions?
