PURPOSE: To improve the versatility of a device for displaying location of traveling object by loading a cartridge card on which a memory storing the control program of a video game device and matching circuit which matches location measuring signals to map data, and a memory storing a matching program are integrally constituted on the video game device. CONSTITUTION: When a cartridge card 3 is loaded on a video game device 4, a receiving section 2 receives location measuring signals sent from satellites and inputs the data to the card 3 through an interface circuit 3a. When the data are inputted to the card 3, a matching circuit on the card 3 collates the data with map data stored in a memory in accordance with a matching program stored in a ROM memory 3c provided on the card 3. A key pad 5 selects coordinates of the location and map data of a scale and displays the map indicating the present location of a traveling object on a display device 6. |
