This is the Scosche kit that comes free with an order from Crutchfield. Their part number is 142GM1596B.
It looks really grainy in the picture but in reality you can hardly tell the difference. However, if you do look closely it is visible that the structure on the kit is rougher. Personally it does not disturb me. The kit has two holes in the lower cubicle part (inside at the back corners) that might be practical to slide a wire through for an ipod or something in this direction. It is an ISO mount not a DIN mount, that's what the installer said but I didn't really understand the difference except that it seems to involve a different position of the screws. Nonetheless the Alpine mounted just fine.
