hmmmmmmmmm........(with a blank stare)
I guess what you're suggesting is that I have a partial failure in my ignition system, and thats causing the whine.

....I wouldn't even know where to begin to solve that issue.......

apparantly, this isn't a common issue with the Ipod interface, and there isn't an equally common "fix" which is what I was looking for. Thanks for the replies, and I'll just see what pans out. Maybe next time it's at the dealer I'll have the ignition checked out just for sh##s and giggles...
