- the entire data management unit 31 is also stored on the hard disk 12 as one data file, but its contents are simultaneously expanded in the memory 15.
- Data 32 indicates that the road data, route search data, and route guidance data are updated in units of all data.
- the entire data unit is, for example, road data is selected for the data type of the update data, and when a certain area is designated as an update range, the road data of the entire area stored in the node disk 12 is updated. In addition, all levels of road data are updated. In other words, for data of any of the data types of road data, route search data, and route guidance data, even if update of a partial area is specified, the specified data type stored in the hard disk 12 All data is updated.

That is, when a detailed view of the background data (level 0) is selected for the data type of the update data and a certain area is specified as the update range, the background data of the block corresponding to the specified area of the level 0 is updated. Is done. In other words, at level 0, background data is updated in block units. The reason why the update management is performed separately for the level 0 background data and the level 16 background data is that the data capacity of the level 0 background data is extremely large.
- the data 35 indicates that the telephone number search data and the address search data are updated in a predetermined area unit.
- the telephone number search data is created in the area unit of the upper two digits of the area code, so the data is updated in the area unit of the upper two digits of the area code. . Since the address search data is created in a data file for each prefecture, each ward, town, and village is updated. Data 36 indicates that the genre name search data is updated on a predetermined area basis for each category.
- the data of the data type of the road data, the route search data, and the route guidance data is updated in all data units, and the data of the data type of the background data and the search data is stored in a predetermined area. Update data in units. This is for the following reason.
- Road data, route search data, route guidance data, and the like are data related to road connections and are mainly data on network information.
- the data when it is necessary to update the data of the data type of the road data, the route search data, and the route guidance data, the data is updated in all data units already stored in the hard disk 12. I decided to update.
- data can be updated with a simple data structure that is particularly necessary for a mechanism for consistency between areas.
- the development of control programs for navigation devices becomes easier, and the data volumes of road data, route search data, and route guidance data are reduced, and the processing speed for using these data is improved. .
- route search data For data other than the data types of road data, route search data, and route guidance data, that is, background data related to map display and search data related to search, consistency between regions is very important. It has no meaning. Therefore, it is more costly for the user to update only the data in the desired area.

Update the data as needed. In this way, the user can bring the car to the dealer and update the navigation data of the navigation device 1 only by operating the update data providing device 2 provided in the dealer.
- the update unit is different, it is possible to update the data appropriately according to the data type. For example, when updating data relating to road connection such as "road data”, “route search data”, and “route guidance data", the entire data stored in the hard disk 12 is updated as a unit, and the "background data” is updated.
- the data related to the map display, such as ",” is updated on a predetermined block basis. That is, the update unit of data related to road connection is made larger than the update unit of data related to map display. In other words, if only a part of the data is updated, the whole data will be affected, or all the data or a certain large range (larger than other data) will be updated collectively. This enables efficient updating of navigation data.
- the update unit of the search data may be an update unit smaller than the data relating to the road connection. As a result, it becomes possible to update only the necessary range of the search data, and it is possible to perform the update without increasing the cost.
- Update-related data can be input only from the update data providing device 2 side, which facilitates the update operation.
