RoadTraps Database is Missing Thousands of Red Light Camera Locations

Navigon Licenses Data from RoadTraps.com
RoadTraps.com is missing thousands of locations from its North American database.  Yet companies like Navigon, Garmin and TomTom still charge $4.99 USA Speedcams for the In-App Purchase in the iPhone store.   RoadTraps.com is clearly operated by a company in Europe and have poor information.  The United States does not have as many speed fixed traps like Europe.  Navigon charges $44.99 for the North American app and $34.99 for the USA and Canada versions.  I commend their claim that they are the #1 Database in the World.
