    摘要: Data in an update data format for performing an update of reference map data is formed by storing in each data frame divided for each data type, at least one of: a first group of one or more common map data records to be stored according to the data type of each data frame in a common map data frame after a conversion by a conversion unit; a second group of one or more first map data records to be stored according to the data type of each data frame in a first map data frame after a conversion by a conversion unit; and a third group of one or more second map data records to be stored according to the data type of each data frame in a second map data frame after a conversion by a conversion unit.

    摘要: Systems, methods, and programs store navigation map data divided into a plurality of partitions, each partition having a corresponding partition file. The systems, methods, and programs identify a partition file corresponding to a partition that is to be updated. The partition file has an update-targeted road class The systems, methods, and programs select an update file, the update file being selected from a server file corresponding to the partition file to be updated. The server file is managed by version and road class. The selected update file is selected based on the update-targeted road class.

    摘要: When the navigation apparatus 5 performs a difference update on navigation map data 39 based on difference update data 17 distributed from a map distribution center 2, the difference update data 17 used in the difference update is stored into a navigation HDD 32, when the navigation apparatus 5 performs a total update on the navigation map data 39 thereafter, the navigation apparatus 5 performs a difference update again (S17) by using any piece of the difference update data stored in the navigation HDD 32 of which the version is newer than that of total update data. After performing the update, the navigation apparatus 5 deletes the pieces of difference update data 17 from the navigation HDD 32 that have been stored up to that point in time (S18).

    摘要: A remote navigation device and navigation system which can reduce communications costs by minimizing route guidance data transmitted to an in-vehicle navigation device is configured so that it can obtain guide area information specifying areas where guidance is not needed. When generating route guidance data to be transmitted to an in-vehicle navigation device, the remote navigation device removes the routes which pass through areas where route guidance is not needed, and generates route guidance data for just the other routes. By transmitting only such route guidance data to the in-vehicle navigation device, the amount of transmitted data can be reduced.
