If it's like an '06, the thing just pulls out. You slip a thin blade (like a puddy knife) into the top edge, and gently lever it till one edge pops loose. There are six clips around the edges that come loose the same way.
Place a thin piece of plastic against the dash edge.....gives you something to lever on without marring the dash. Do it on a warm day or use a hair drier to warm the edges. It'll come out easier that way.
Almost all bezels of this sort on all cars come out this way. If you don't see a screw, the thing was just snapped in upon assembly.
