Navigon has been very aggressive about keeping its highly rated MobileNavigator app [iTunes link] up to date. Now, new features are putting it even further ahead of a lot of the competition.

The update adds three innovative features: in-app connection to Facebook and Twitter, Panorama View 3D with 3D terrain views powered from NASA data, and personalized route delivery via NAVIGON MyRoutes, an intelligent direction provider.

For Facebook and Twitter connectivity, a simple icon tap posts the user's current position, destination, and ETA without navigation interruption -- handy for advising family of your expected arrival or updating other travelers with your location if you stopped for a break.

The MyRoutes feature analyzes driving habits, patterns, location, time/day and provides up to three routes clearly displayed in-map with ETA, distance and driving times for each.

The 3D views enable intuitive orientation of the surrounding environment, and show you what lies ahead with digital landscape elevations, shadows, and geographic images. Panorama View 3D is integrated in-map, independent from the phone's data connection. The Panorama View 3D feature will be available via an in-app purchase.

There is a special Macworld promotion of the current version of MobileNavigator for US$69.99 and one time in-app purchase of Traffic Live for $19.99 (regularly $24.99) from February 5-15. All the new features except Panorama View are free updates for existing owners of the app. The Panorama View feature will be $9.99. All the new announced features are expected to be available this spring.

Besides being available for the iPhone 3G and 3GS, the NAVIGON app also runs on the first-generation iPhone or an iPod touch. Additional accessories are required for GPS navigation on these devices.
