<p><P>PROBLEM TO BE SOLVED: To provide onboard terminal equipment for turning the updated contents of updated map data to different display forms corresponding to a representative fraction. <P>SOLUTION: When displaying data for updated condition display transmitted from a distribution center 200 on the display monitor 119 of onboard equipment 100, if the representative fraction is small, the icon 50 of an asterisk is displayed at a prescribed position corresponding to an updated mesh. When the reduction scale ratio is increased, the icon 50 disappears and the updated mesh and an already received and updated mesh are displayed by changing background colors. When the reduction scale ratio is increased further, the updated contents are displayed concretely. For instance, a newly constructed road 61 and newly constructed facilities are displayed by the icon 62. Further, it is detected that a vehicle is stopping and updated information contents can be displayed in a list by characters. <P>COPYRIGHT: (C)2004,JPO</p> |
