NAVIGON has submitted a new version of MobileNavigator, v1.4.0, to the App Store. The program provides turn-by-turn navigation similar to the company's stand-alone GPS devices. It functions in portrait and landscape modes, and includes voice directions as well as simulated street views.
The v1.4.0 release will have 13 new features, including an enhanced pedestrian mode for navigation while walking. A new interface will take advantage of the compass in the iPhone 3GS, shifting map position in tandem with a user's orientation. Google Local Search should meanwhile allow quick access to subject and place searches, with matching directions.
