It is as Mike says Ken, but from your question I would think that you have never been behind the center waterfall where the power key cylinder lives?
Just in case this is the first time you have the need to remove the radio & A/C & DIC dress plate I would just give you the quick run down on the job. Forgive me if this is not the case.
The center A/C register has two screws that have to come out and then the register is free.
Shifter/ash tray console and the center A/C system register have to come off first before you can get to the fasteners that hold the radio bezel in place at the bottom where they meet.
Shifter console can be lifted free by locating the screw ( just 1 ) under the cup holder/ash tray fillers, and the 2 screws just inside the console door under the felt at the extreme fwd end of the compartment. Some say that the console can be moved enough with out pulling the shift knob? I have never tried that. You need the shifter/ash tray console out of the way of the bottom of the radio bezel as there are 2 screws hiding at that bezel's base.
To get the shifter console out completely ( which is what I do ) the pattern plate is plastic so be aware. Small thin screwdriver and pry it up & off the knob. Under it is a metal wedge shaped like a T. I use a 6" pair of vise-grips with a stout screw driver thru the jaw gap and wack the screw driver shaft alternating blows and the "T" will come straight up. Next unscrew the knob and then on the reverse lock collar is a 1.5 mm (?) hex screw to back out so that collar lifts off. Now discon the plugs for the light and lighter, and the shift console can be removed & placed aside. Oh, mind the hex screw torque as it threads into plastic...
Now the radio/power key bezel has 2 screws at the top where the A/C register was, and 2 at the bottom where the front edge of the shifter console was....having too much fun yet? One note of caution on this bezel. There are two spring clip fasteners that insert into bosses, L & R sides, at about the level of the radio opening. You have to work your fingers under the bezel plastic a bit to make sure you apply the pull near those clips or you could break the bezel in half. Once all the screws are out and you pull on the sides of the bezel the location of those spring clips will be easy to locate. Then you must discon the plug to the power switch and the bezel and switch can come free and the clip should be lying somewhere just behind the removed bezel.
As the FSM says: "Assembly is the reverse." Just be mindful of the spring clips as mine took a bit of force to get out and back in so pressure in the wrong area of the bezel might have a very bad result.
