A map updating system, which includes a navigation apparatus in a vehicle and a map server, includes a driving history database storage storing driving history data on the vehicle. The map updating system determines, based on the driving history data, a location visited a predetermined number of times or more as a first destination; determines, based on the driving history data, a route which was used a predetermined number of times or more among routes used to visit the first destination as a first route; determines a second route that is to be used to visit the first destination when a part of the first route is unusable; and updates map data in the navigation apparatus in order of (i) data on the first route and second route and (ii) other data. |
