SOLUTION: The screen of the display device 7 is divided into the plural areas and the map of the registered spot is displayed in the respective areas. A control part 17 reads the map data of the neighborhood of the registered spot among the map data stored in a CD-ROM 1 to a buffer memory 11. A map plotting part 18 segments a rectangular area whose center is the registered spot from map images plotted based on the read map data and prepares map images for list display. A screen synthesis part 23 synthesizes the map images for the list display inputted from the map screen part 18, generates a registered spot list for which the screen of the display device 7 is divided into eight areas and the images for the list display of the registered spot are displayed in the respective areas and displays it on the display device 7. |
