There is a company called Arkon, and they make PDA mounts. There are a bunch to choose from. I have the one that is a flexible stalk, and it mounts to the passenger seat bolts. Although made for a PDA, I have found it works for my sat radio, my GPS, etc., so I would imagine it would also work for an IPOD. The picture shows my PDA mounted in it, which at the time was also serving as a GPS... It might work for you. The beauty of it is, if you don't like it, easy to undo, just unscrew it.
