This is what I'm trying to figure out.

I have a ipod video and just to have ipod control (no video) I still need the special ipod cable?

So glad I found this out before I spent money for this Nav unit.. I only wanted one built in so I wont have to use tomtom on my phone while driving.. I guess it's back to finding one that's not overpriced and has decent nav
