If you are the type that likes a 10″ display for driving navigation, TomTom just updated its $59.99 iOS turn-by-turn navigation app to be universal and optimized for the iPad. You’ll of course want to have a 3G version of the iPad/iPad 2 or be tethered through an iPhone that can share GPS.
TomTom also hints that a new version with some interesting features is on the way:
iPHONE 3G USERS: THIS IS THE LAST VERSION OF THE TOMTOM APP FOR iPHONE THAT WILL FULLY SUPPORT YOUR DEVICE. You will be able to download and use the next version of the TomTom App but new features will not be available to you.
