The global positioning receiver communicates with a system of satellites and provides continuous data, reflecting the present. spacial position of the vehicle in terms of its latitude/longitude coordinates. The interface between the GPS receiver and the wireless telephone includes a speech synthesizer circuit which converts the digitally encoded spacial coordinates into speech, which enunciates the position through the cellular telephone. By calling the vehicle cellular telephone from a remote location, the owner of the vehicle can hear the location of the vehicle, and then use that information to obtain its precise location.
