If you find a good installer they can put just the faceplate there then you can put the HU in the glovebox, or under your seat or something. I wouldn't try it myself B/C i dont want to pay if i screw it up. That would be awesome i think - then have a monitor or the factory HU in the origional Hole.
so you could leave the HU in the console and just have the faceplate put in a little console on the roof - that would be awesome. Just make sure you get a good reputable installer if you want to do this - most places wont back up this kind of work.
shave what? Handles and stuff - they are easy, get everything wired up (poppers/solenoids and whatnot) Cut sheetmetal to size of handle, weld in place, grind, smooth out with fiberglass body filler (if the metal was right you should not need much of this stuff), sand, prime, take to get repainted. I tried this for the first time on my S10 tailgate and it was way easy.
