The TomTom iPhone app is one of the better navigation apps on the App Store, but it just got even better, with the ability to purchase their Star Wars voices within the app. Purchase the app, you shall.
Darth Vader, C3PO, Yoda and Han Solo are all available to purchase as an in-app purchase for $7.99 each. The update also includes some improvements for the navigation side of things, including navigating to geotagged photos and retina display support for iPhone 4 owners.
The app is worth $90 in the app store… Pricey, but significantly cheaper than a dedicated satnav. And you can get directions from Star Wars characters. Surely that constitutes a win?
