I have the AVIC-D3 in the car and working.

The trouble is I can't get a dash kit to work for the life of me. The Scosche and Metra kits both have a rectangular trim piece that directly surrounds the head unit. On both of these dash kits I cannot get the trim piece around the head unit. It is much too small.

Is this a common problem? I looked at it and I would need to do some serious trimming and sanding to get it anywhere near the right size, and frankly I am not sure it is even possible.

Is there a simple trick I am missing or something?

I got mine to work in an 07 tacoma, there should be another piece that goes in between the d-3 unit and the dash piece. This may or may not help.

I'm using the socsche kit and it fits with no problem...
