As the name suggests, the Point-Of-Interest-Warner visually and acoustically warns you of POIs as you approach them. Consequently, POI warner is the ideal solution for notifying you of SPEED CAMERAS that might be on your route*!
Although POI-Warner is ideal for Speed Camera use, it can be used for other items like being warned of ANY kind of Point of Interest. But not enough! POI-Warner allows you to visualize your own Overlays on the map, to simply record new POIs on the road and to synchronize your POIs with an online server.
(*): please refer to the restrictions of your government, the usage of a speed-camera-warner might be restricted or interdicted in your country.
