Vent trim rings= Be CAREFUL, they are just held in w/ wicked small clips molded onto them. I broke a few on each one but they still hold perfectly fine. Just pry gently on one side. They hook behind the dash pad.
The plastic piece (turbo timer spot) is molded to the rest of the center top part. After you get the bottom and the cup holder out, pry the vents out (stick a flat blade screwdriver between the vent and the housing and pry inwards) and IIRC there is a screw or 2 in the top or bottom??? It's been awhile, someone correct me or not. That should be it, this was done on my 03, but I believe they are setup the same.
