I parked my car in the sun on a warm day. I pried some of it off with my fingers, and used fishing line to 'saw' through the adhesive on the rest. I also wasn't worried about keeping them and when prying some of the CF broke, but it was yellowed and looked like crap anyway. Then I did the finger rub to get most of the adhesive off. I then put some goof-off on a rag and held it on the adhesive for a bit and rubbed some more. After I got it all off, I cleaned the whole dash with some 303 protectant.
As for what it looks like without it on there, it looks like a normal dash. The small icons for the closed vent and open vent are underneath the cf trim.
