On our trip to Lemans I used used the tomtom app for the Iphone and I must admit it worked far better than I though.
I linked the phone to a set of bluetooth wireless ear phones which seemed to work a treat.
I'd give some thought about what to do with the phone and wanted it somewhere where if necessary I could look at the screen so I went for this
Quadlock and simply fitted the locator to the dash. I'll post a picture later.
Quadlock should in the next month or so be bringing to the market a fully water proof case, but with the rain we have in Lemans the iphone didn't suffer.
I should add that I've modified the phone mounts for my other vehicles to take the quadlock as well, and I'm currently trying to work on something for the aero.
