Avertisseur radar "radar warning": Vive le Navx, a la trapster
Navx is a €1m a year French company whose business is speed radar location databases. In France, it is illegal to sell or use selling radar detectors, devices that pick the microwave or laser radiation emitted by speed guns and automated cameras. But providing speed trap location data is lawful. In fact, the French Interior Ministry maintains a public database for fixed radars. And companies such as Navx, or various GPS makers supply location information for mobile radars.
