I got a Pioneer AVIC F-90BT. double din, with bluetooth and navigation. And I got a Kenwood back up camera.
I installed it all myself, its what I do anyway.. I also built the dash piece as well, its my first one.
Its really not that bad to do, I've put double dins into harder cars before.
I got a dash piece from a junkyard, the guy just gave it to me. That way I didn't cut up my stock one. I cut out the top and bottom and cut some ABS plastic for the sides. I tacked in the abs with some super glue.
I then used some abs weld and let it set overnight. One thing i did to add some strength is cut about 6 small triangles to brace the back side of the abs, sorry I forgot to take pics of that.
Then when that was dry I filled it in with bondo.
Once that dried, I used some glazing bondo to smooth it out. It takes a bunch of sanding to get it all smoothed. I primed and sanded twice before I finally got the smoothness I wanted. Then sprayed it textured black.
It looks good to me, and that textured finish helps to fill in any imperfections but I think I may go back and try to match the gray with interior paint instead. I just don't like how it feels.
This is the finished product.
These are all camera phone pictures too, sorry for the bad quality.
