Suggestions to mount iPhone 4S above NAV radio for music and using it as nav on E53

[nostra]

My wife is looking to mount her iPhone 4S above her existing NAV radio, possibly over the left vent, in order to use the iPhone for GPS nav and music input as well as be charged from that location. Any suggestions on what to use to do this?

She suggested using the ProClip Center Mount 853656 ($30) to mount over the left vent just above the stock NAV radio and
Adjustable Holder with Tilt Swivel and Pass-Through Connector with horizontal support ($80)

I have the Intravee II setup that is now being re-installed with a new firmware update. It was flaky when I bought it a couple of years ago, so took it out. I think with a cleaner mount setup this will be received well versus going out and buying a new Mediabridge for the added bluetooth connectivity (not needed).

With the currently installed NAV system, it's slow, has outdated maps, doesn't have Sat radio, so ultimately the iPhone 4S would be a much more modern music and nav interface.

Any good suggestions other mounts to cover this need? Or strong feeling about mediabridge vs using the Intravee setup? If you have pics, please add them of your setup as well. Thanks!
