Just take that whole black piece (that goes around the radio, climate control out, then drill your hole and put the led that way, those parts are connected with the rest of the bezel.
agreed, you need to remove the whole thing. I just replaced the entire area myself. to do so you have to pop out the hazard light and rear defroster sections (you'll find a screw in each hole). Also you need to remove the panel below that area where your cig lighter is. there are two screws on each side up in there that are tricky to get to but can be done. unclip a couple of wires, drill your hole and reverse the above steps to put it back together. If you need me to I can take some pics of those hard to reach screws but I hope you can find them without me having to take apart my car.
The easiest way to be able to get the cig lighter panel off is to remove the glove box & the panel below your steering wheel, its alot of removal but doesn't take that long at all...
