Somebody just posted in another thread about doing that. If i see it again I'll post it here. The center scoop one on my car had a tab underneath that you had to release. Once you released that tab, you could pull and rotate the bezel up and out of the hole. there was also a piece of double-sided tape holding it on as well, but that gave way fairly easy. I think it was more there to keep it from rattling.
I'm guessing that your should be similar.
