An area or desired kind of service is inputted through an input device (110) and transmitted to the data base (100) through a transmitter-receiver (116). When an area is inputted, the data base (100) retrieves the information about the service facilities in the designated area and transmits the information to the terminal. When a desired kind of service is inputted, the data base (100) transmits the information about hte positions of the pertinent service facilities and the electronic controller (ECU) (114) of the terminal calculates the distribution of the service facilities on a map, selects the area which meets most the inputted condition, and displays the area on a display device (12). A GPS navigation system (112) searches the route to the selected area and prepares a travel plan.
