I did something similar, but I remounted a hidden cigarette lighter socket to a constant 12V source and grounded it twice for stability, so my phone and MP3 player can charge while I shut the car off and go inside a store for a second (don't leave it connected overnight though!). I ran the wires behind the dash, but I use one of my air vents that rotates all the way around as an able-to-be-completely-destroyed mounting location, then just cut a piece of wood to re-mount a new cell phone holder, etc.
For the Atrix dock, I pulled off all the suction cup mounting materials so it was just the threaded socket on the dock. I used a large enough drill bit to cut into the wood in the right spot for the threads to fit, and threaded them onto the wood to test. Removed it, sanded the wood down smooth on all edges, and applied texturized black spray paint to the wood to make it look like plastic instead of tacky looking wood. Mounted the car dock to it again after drying, and now the dock rotates with the unuseable air vent from portrait to landscape!
Hey, I've got a 2004 Acura RSX, it isn't a BMW.... works just great!
