CONSTITUTION:A transmitter 1 of each utility 100 sends utility data representing information relating to each utility 100, and when a receiver 4 in the navigation device 200 installed on a mobile body receives the utility data sent from the transmitter 1, an analysis means 5 analyzes the utility data. A picture drawing means 10 generates a display content based on a current position of the mobile body measured by a position measurement means 6, map data read from a map data storage means 9 by a read means 8, and utility data analyzed by the analysis means 5 and a display means 11 displays the display content. Thus, the user of the navigation device acquires the information relating to the utility together with the map data and the current position of the mobile body by having only to observe the display content. |
