I did a lot of cutting behind the dash to make room for wire runs and modules. It looks great once the screen goes in though, like it is meant to be.
I cut out any plastic that was not critical to the dash, made plenty of room for the giant heap of wiring it took to get all my extras in. Most of the stuff is sitting in the very bottom of the center console, but I had to make room to get everything down and for all the wiring. Your going to want a good AC dremel and a plastic bit.
