Nice one Stewart but seems a bit over engineered for the job ? I simply use one of those with a big rubber sucker mounts for £4.99 or less and stick it on the dash or speedo, put a lead from the iPhone into the fag lighter socket and away we go.
Usually I have the sat nav on the phone on voice directions and the speedometer app on view.
I wanted to avoid the whole sucker thing as ruins the look of the dash
I wanted any technology hidden away where only I can see it
