You can add augmented reality to the feature list for the Navigon app. The company calls it Reality Scanner, and it shows destinations and nearby points of interest by superimposing that information over a live camera view. This is a feature best used by pedestrians; I'd hate to see someone driving and waving his iPhone around to use this.
Navigon is also adding what it calls Safety Camera alerts, which is a way to warn drivers of speed and red light cameras along the route. The information comes from the RoadTraps data base. The app works with US speed and red light cameras and is available as an in-app purchase of US$4.99 for a lifetime subscription. Navigon is also adding Traffic Check, which provides a quick graphic that appears after you plan a route, detailing traffic jams ahead of you. There is no charge for this service, and it does not require the paid Traffic Live feature to work.
MobileNavigator North America apps are on sale for $15 off until April 28. That would bring the USA version to $34.99. Traffic Live is on sale for $14.99 for a lifetime subscription. The Navigon app works on the iPhone, iPad and iPod touch. Check the gallery for some screen shots of the new features.
