I want to setup my iphone 4 so that I can plan a route (backroads) and have the app voice navigate it so that I can concentrate on the drive.
Any help would be appreciated!

 

Buy a Garmin/Tom Tom/other sat nav but be careful to choose a model which has Itinerary/Custom Route planning.

Download this software: http://www.benichou-software.com/ind...emid=2&lang=en and you can pre-plan routes which you can upload to the Sat Nav of your choice.
