Not only has Navigon added a bunch of new features to its iPhone app , the price is $20 cheaper—although if you want Traffic Live and 3D maps, it still adds up to $100. Nonetheless, it sounds worth it. The update has a few nifty angles—there’s the connection to your Facebook or Twitter accounts for updating friends on your current position, destination and time you’re due to arrive; the aforementioned Panorama View 3D views (which use NASA height and terrain data) and personalized route delivery, called MyRoutes. The addition of NASA’s data is a nice touch, meaning you’ll be able to find out more about the location you’re in, such as elevations and shadows. Discover a hill before you reach it—and maneuver around it if you’re not keen on heights.
