摘要： The system of the present invention provides easy update of a database containing a large amount of data arranged in a complicated interrelationship by use of a data file of a content limited to data differing from that already in the database, within a relatively short period of time. The system includes a navigation apparatus having a local storage database which contains, updated by a difference data file, a plurality of data groupings. The navigation apparatus determines conversion priority according to the operational state of an operation program and converts data in a local storage database to a referential data format in the order of the determined conversion priority. The system also includes a server apparatus for outputting the difference data file to the navigation apparatus.
