No problem, the bezel I am referring to can be found here:
www.MyBimmer.net. Its probably the cleanest thing you can get that is available, but I do believe Rich is making an updated version. There are no brackets or mounting material that come with the bezel, so who ever installs it would have to custom mount it and secure the bezel + HU with some custom fabrication, but again, nothing an experienced installer should have trouble doing.
I will be installing mine shortly (Pioneer AVIC-F90BT), I will try and snap some shots of the installation process, as I have not seen anything very detailed on the board.
Good luck!
