Abstract: PURPOSE: To easily input the position of a destination, etc., with telephone numbers by providing a list to make position data composed of information about plural positions, position data storage information, and the telephone numbers correspond to each other. CONSTITUTION: When a telephone number is inputted under a position input mode, a processing part 5 reads in a telephone number list 7 of a storing part 6, executes matching processing for the telephone number, reads the block of position data 8 from a block number, and holds position information having a matched position number. In a route retrieving part 9, when respective pieces of position information about a starting place or a present position and the designation are held, a route is retrieved, and the optimum route up to the destination is set. Further, a distance detecting part, a rudder detecting part, etc., to trace a traveling present position, are positioned under the processing part 5, the pieces of information of these detecting parts are processed, and route data are generated in the processing part 5, and route guidance informa tion is outputted through a display part 1.
