It has finally happened, for most people negating any real need for a stand-alone GPS unit for the car.
Do a search for "TomTom" in the App Store for the following map packs:
- U.S. & Canada: AUD "19.99 - Western Europe: AUD "69.99 - Australia: AUD $99.99 - New Zealand: AUD "14.99
Of course, if you're really keen, you'll just hang-out for their retail kit. It includes the app itself, a GPS-boosting receiver, windshield mount, car charger and speakers and should hit shelves at around $249.
