I am posting this for other Bluetooth PDA Phone owners who are seeking a way to free up the cup holder and ash tray and use an aftermarket PDA Phone cradle to hold and stow.
I own a Blackberry 7290 with Bluetooth however, a solution from ProClip is available for many PDAs and phones.
Pictured below is the solution I installed in my 2005 X5.
You will notice that I use the Blackberry car charger in the power port found under the glove box. I had no idea it was there until I started fooling around with the BMW in-glove-box power cable extender.
I found a clear cable clip at a local hardware store to hold the power cable in position to keep it near the ProClip base.
A side benefit as you can see in the picture is the ProClip product doubles as a way to hang a garbage bag in the passenger side foot well without being intrusive.
You will need two ProClip products to replicate this solution.
1) DEVICE HOLDER: The
http://www.proclipusa.com website has a wizard to take you to the correct holder for your phone unit.
2) VEHICAL MOUNT: The phone holder attaches to a base stand. This base stand or vehical mount snaps right in without any drilling or trim modification. For an X5, you need Item No. 832843.
Drive safe and watch the road!
