One of Android's key selling points when combating the iPhone is the free turn by turn navigation provided by Google. The iPhone does not currently offer a free turn by turn navigation application. Yesterday, Navigon launched its MobileNavigator application for Android. You can purchase the application in the Android Market for $59.99, but why would you?
The MobileNavigator application does bring some functionality (tricks?) to the table that the free turn by turn application that Google provides does not offer: Things such as a Reality Scanner, this will let you aim your phone's camera at any point of interest and it will help you find out more information. That is all the detail they really go into on that feature, though there are quite a few standalone applications that do similar things.
And Navigon describes two more unique features: Reality View Pro "brings enhanced photo-realistic 3D images of interchanges and intersections," while the Traffic Live feature "uses crowd-sourced traffic data from other device users to provide real-time traffic information and offer up to three alternative routes and travel times." Some will no doubt be thanking the crowd for the advance red-light camera and speed camera warnings.
At the end of the day, one still has to wonder why you would spend $59.99 for an application that offers some unique features. Are they really useful enough to justify the price? Let us know what you think in the comments.
