I've attached a pic that explains it. The Allen head is either a 20 or a 25, I don't remember and don't have the instructions I used handy. I looked for a scan of the Crutchfield instructions like I have and couldn't find them.
Anyway, it's easy as pie. The trim surround for the head unit just clips into another piece of trim (the one below it around the AC controls) that is screwed into the metal frame.
Hope this helps!
