This is a very simple thing to do. Here are the steps.
The plastic surround is held by clips. Carefully pry it out from the bottom, with a flat head screw driver wrapped in tape to prevent scratching. Once this is out, you will see a metal cage surrounding the radio, held by four phillips screws, two on each side. Removing this will allow you to separate the metal cage/radio unit away from the dash. Then unscrew the phillips screws on the side of the bracket that are screwed into the radio, undo the harness, and voila, the radio is out. (Man, how many times did i say screw in this paragraph!)
