I found this double din CD player with GPS and a back up camera on amazon for a pretty decent price (I remember when a new car stereo was $$$)

and this neat kit mimicks the factory piece, but has the large opening for the double din, and comes with a wiring kit to make wiring the two easier.
It's amazing all the neat accessories and support these things have...
