I've desperately tried to make my iPhone work as my GPS etc. I purchased a Ram mount for the iPhone a Powerlet socket and specific charging cable for the phone. I was so sure it would work because I use it in my car all the time. It works well in populated areas and with no gloves unless, you're a bit sweaty in your leather gloves then you can touch the screen and get a few things to function. The google map function just could cut it. I purchased a few GPS specific apps and it did slightly improve but, not enough to make me want to use it all the time as a GPS. As a Bluetooth entertainment device for music even pandora radio it works very well.
