What did you go with for radio/trim? Mine's a 2009 so not in the years covered with this factory kit, at least at this point.
Just used crutchfield, and a few internet vids.
Relocated the climate controls to the lower pod, then toss out the CD holder, and it is a nice double din space.
Then there is a bezel to trim it all to the edges.
Also adding video in (std def) and two USB ports to one of the blank switch pods.
Also, also, back-up camera.
