Abstract: The navigational system, device and method of the present invention provide navigational information to the user derived from data signals received from a plurality of transmitters (20,22,24,26). The range to each of the plurality of transmitters (20,22,24,26) is then computed based upon the corresponding data signal received from the transmitters, and a current position relative to each of said plurality of transmitters is then determined. Geographical data relating to at least the current location of the user module 32 is stored in a memory 40, and selected geographical data relating to the current location of the user module 32 is retrieved from the memory 40 to provide an audio or video display 44.
