An automobile equipped with a Global Positioning System (GPS) receiver and an on-board computer is configured to transmit the automobile's location and direction of motion to a central server. The central server is configured to identify the automobile, the route taken by the automobile. The central server obtains location information or geo-related information pertinent to the route taken by the automobile, filters the data according to certain criteria, and then delivers an audible version of the filtered data to an audio output device such as a radio receiver located in the automobile.
