I have the Metra 99-8220HG and it fits and looks perfect. I also have 2 Scosche kits and they both look terrible with a huge gap at the bottom where it meets the a/c controls. Scosche may have fixed that issue with their newer ones but the old ones didnt look very good.
I've got the Scosche kit in mine; fit and finish is fine as is the color match. If I had to do it again however I'd probably get the Metra because the much deeper inset of the Scosche makes the small knob on my headunit (Avic-F90BT) hard to grab.
Haha, I've been trying to figure that out as well. The question has been asked 3 times and still hasn't been answered.
I just installed the Metra kit in mine and it is pretty good. Fit is good but not quite perfect (I'm extremely picky). Finish is darn near perfect but there are a few minute flaws, including a slight waviness in the molding. I also had to trim up the included trim bezel a bit because it was making contact with the faceplate of my AVH-P4100DVD when it would open or close. I might just try the Scosche kit for comparison so hopefully they've worked out their kinks.
