Navigation system map updating takes the actual positions and notes deviation from the displayed route, to obtain a new route from a remote server

摘要

The operation to update the map, in a navigation system (No), the actual position of the navigation unit detected by a global positioning system (GPS) is compared with the route shown on the map. Should the position deviate from the displayed route, by more than a minimum value, the positions are stored as a new route (Soneu). The navigation unit has a wireless communication link with a server, for the new route to be transferred to the infrastructure components.
