I think I found the instructions on one of the Honda forums. I should have bookmarked it because at some point I am going to have to put it back.
I think there are 2 screws inside the center console you need to take out, from there you can pry a screw driver along the edges and it pretty much snaps out. There were also a couple screws in the cubble hole that need to come out as well.
I used the RH96 bracket, no DIN sleeve. I used heavy wire ties to attach the bracket to the metal mount, mine kept flopping down, so I also have an 6 inch bungie chord which you really can't see that keeps the radio from moving around.
