The passenger side piece and drivers side piece is really easy to remove. I just updated my dash to the 2012 style, and added the suede insert with red stitching. I hope I don't get bubbling on that.
So anyhow, you remove the side panels on the dash. Reach in from behind and pinch the first clip for the dash while pulling. Get that trim off. Remove the 2 - 3 7mm bolts. You should also pull the gauge trim out a bit, then pull the passenger piece off. It is merely clipped into place.
Once that is out you need to unscrew the center duct then reinstall it on the new dash piece.
It may take longer if the dealer pulls the HVAC controls out.
