Friend tells me his Ipod keeps locking up when he plays it with the unit stored in his windshield pouch on his Ultra. Said I hadn't heard of that before. Well, I'm riding my Ultra and the same thing happened. The hard drive locked up. Couldn't get the song to stop or play. Couldn't turn off the unit. Had to sync it to my computer itunes to fix it. I noticed this after I stopped for gas. Possibly turning the ignition off and on with the Ipod playing had something to do with it. Or not. Has anyone else encountered this? If so, how did you fix it? Thanks!
