I find that the iPhone is too small and requires too much attention to fiddle with safely while driving. Mine is in a dash mount and hooked into my car's built in hands free phone setup, but whenever I need to use it for navigation I generally pull over, wait for a stop light, or ask the passenger to do it. I then set up the nav app to give me turn by turn spoken directions so I don't have to fiddle with it any more. Using the built-in google maps app for navigation is not safe.
