I havent seen a writeup, but it isnt that difficult to take apart.
Remove the heater control knobs, dont lose the clips like I did.
Then the heater face plate pops off, also remove the ashtray.
The ashtray mount comes out next, two screws in vertically.
The cover over the radio is mounted with 3 screws and two clips.
There are a few plugs for the 12v outlet, and the ashtray light.
Then I swing it up and over my steering column, I leave the airbag switch alone.
There are 4 large phillips screws mounting the radio, and most double DIN radios reuse stock mounts, screwed on the sides of the new radio.
The harness adapters work really well, I think I have a pic of one somewhere....
The harness came from Wal-Mart, a bunch of butt splices and a couple of other wires and i was up and running.
This was the radio I removed to install my DNX-5120, it worked well.
