Navigon will be releasing an iPhone PND app called MobileNavigator, with support for Real Roadsign Pro, Reality View Pro and Lane Assistant Pro. There are also POIs (points of interest) that can be displayed optionally along the road, and portrait or landscape orientations for iPhone 3G and 3G S display.

Both the Lite version (with no directions, but browsable maps and POIs) and the full version will go on sale June 17th, through the App Store. No pricing available yet, or whether there’ll be an optional car kit.
