I've seen a bunch of D3,Z2 installs which replace the radio unit but, I have yet to see one installed in the upper cubbyhole. I know that for 03-05 models you can purchase a new cubbyhole with the 03 door and framing but unfortunatley that won't fit in the 06's. For those who have done it, what steps did you take to install yours or did you guys do custom fabrications? Thanks guys.
