1. A navigation method for providing navigation by using map data, comprising:
- displaying a menu with which a user specifies an area of a map over which map data are to be updated, the menu containing a map-based option for area specification and a route-based option for area specification, the map data being managed in units of a mesh;
displaying a route and a map including the route, and displaying along the route one or more meshes including map data judged to be updated based upon the route, when the route-based option is selected from the options in the menu on display;
making a display in which a data update instruction can be inputted;
obtaining update data along the route when the data update instruction is input; and
executing processing by using the obtained update data.

5. A navigation method to be used in a navigation system that uses map data stored in a fixed recording medium and update map data downloaded from a map data management apparatus in combination, comprising:
-
a step of prompting a selection in a map data update menu prepared in advance, obtaining an input indicating the selection and displaying a specific area for a data update; a step of prompting an input of at least one selected option in an update category menu prepared in advance and displaying the specific area distinguishably when the specific area is judged to have update map data based upon the input of the selected option; making a display in which a map data update instruction can be inputted; obtaining the update map data of the specific area having the update map data when the map data update instruction is input; and using the obtained update map data. - View Dependent Claims (6)
