There are two trim pieces on either side of the radio bezel that have to come off. Pull carefully so you don't break and of the clips. Then the radio bezel comes of the same way. Then there are a few 7mm or 9/32" bolts that hold the radio in. You need two antenna adapters I will put up the part numbers while I'm at the shop on Monday.
Its really easy..The long trim piece on the right side is easier to take off if you open the passenger door and start at the very end of it. The other one is a little trickier, just be careful to not pry with anything like a screwdriver cause it will leave marks in the dash (I did that) If you can get it started then you can pry it off just enough to see down inside and get a small flathead screwdriver, stick the screwdriver inside the clip and rotate, they pop right off when you do that.
