has anybody seen this or used this?  

I haven't used one of those, but I would imagine it's the best alternative short of buying a deck that supports iPod interface. I have heard that the units that plug in like a changer will only support a few playlists and of they won't show playlist and song info like iPod compatible decks will. I would however think that it will give you far superior sound quality than the FM transmitters which are just about worthless.  

Yeh I agree with mike the FM transmitters are garbage altho there is a really really good one that wraps around your whole iPOD I will try to find the info on it. and thats almost as good as gettin a jak instaleed in your ride
