Thanks guys - I'm quite happy with the result myself. Removal of the radio and the CD player was pretty easy, actually. The instructions (in the Bimmer link I mentioned) show the removal of the multi-info display and the radio.

It took a little patience after twisting the small screw and pulling at the right angle to remove both, but you will be able to "feel" it out as you go. I'm not a big DIY'er, and my wife was VERY nervous about my project. But, I knew I could always run back to the dealer with my tail between my legs, and ask for help.

One final note I just remembered - this kit was for a NON-NAV, with the Business CD player. They have similar kits if your BMW has NAV, and I would assume the instructions differ slightly as well.
