Navigon just recently rolled out a stylish iPhone Car Kit for use with its iOS navigation app, and it's now also announced a fairly significant update to the app itself. In addition to all the usual basic navigation features, MobileNavigator 1.8 now also boasts an augmented reality component dubbed the "Reality Scanner" that overlays points of interest on top of a live camera view, as well as a new "Safety Cameras" feature that warns you of speed and red light cameras (available as an in-app purchase for $4.99). What's more, Navigon has also dropped its prices across the board for the occasion -- the full app with maps for all of North America will now set you back just $45 until April 18th, while versions for just the US or Canada run $35 apiece. Full press release is after the break.
