You might try the engineering menu shortcut when the Sync get stuck. I haven't had that happen to me, but it's worth a try. Hold eject and next track for about 2 seconds; it may be easier than disconnecting the battery or pulling a fuse.

WARNING: The engineering menu starts a speaker test in a few seconds if you don't cancel it, and it's very loud. You want to cancel that.
