The silver piece surrounding the radio and hvac controls will have to come out.
Look at the bottom of it and inside your glovebox door and under the knee panel under your steering wheel for screws. It's probably got a couple of screws holding it on. After you find those, you'll have to pry off that surround. It's held on by Legos. Your radio mounts like this one. Four screws and some alignment pins. Whoooooo.
