I saw this product in one of the postings and thought I would order one. I drive 1500 to 2000 miles a month and wanted a nice vehicle mount for my 7520. I have to say that I'm impressed. I've had a few other cell phone mounts and the were always cheap looking and not very sturdy. The center mount and swivle holster are very high quality and look good great. I don't have one of the extended batteries yet but it looks like the BB would fit in the holster. It was $75.40 shipped, so it's a bit pricey. http://www.proclipusa.com/
If your looking for a nice professional looking mount that doesn't damage your car, this is the way to go. Especially nice if you have TeleNav.
