Abstract
PURPOSE: To display a map on a display device immediately after turning on the power source of a vehicle by storing just preceding collection data in a second storage means in turning off the power source of the vehicle and displaying the map based on stored data in the second storage means in turning on the power source of the vehicle. CONSTITUTION: When an accessory switch SW is turned off, a CPU 6 stores map data, which is temporarily stored in a RAM 8 in the fall period of the output voltage of a regulator 18, in a second storage medium 10. Map data in the RAM 8 and that in the storage medium 10 are stored in a consecutive form for map data in a first storage medium 9. Thus, map data is read out from the storage medium 10 in turning-on of the accessory switch SW to quickly obtain the map data with the current vehicle position as the center without collecting map data from the first storage medium 9.
