I would recommend getting the Kenwood 7015 at the best price you can find. There have got to be some good deals. I know Crutchfield is like $200 off or something like that. I don't think the enhancements on the new model are going to make that dramatic of a difference in every day use.

To my knowledge (just to add to your confusion), Alpine has probably the best iPod interface out there, but I don't think they have a double-DIN full screen headunit, unless there is a new one out this year.

And as I mentioned earlier, the Eclipse AVN5435 is an all-in-one unit including the navi, and it has aux inputs for your iPod. My guess on price at a dealer is about $2000. I don't think you can go wrong with this unit.
