Iphone to car.....

Well, had a bit of time spare so played about in the garage.  I removed the belt clip from the retaining clip and then used cable ties to attach it to the roll bar:

 Used an old retaining strap I had laying about to secure it even more.

Only issue I can see already is the fact that I can not charge the phone while using the camera app.

Hoping to give it a trial run in the next day or so!!
