First Claim
Patent Images
1. A method for performing a vehicle navigation along a road system using a navigation device, comprising:
- receiving a destination input from a user of the navigation device;
prompting the user to insert a first data medium containing navigation data, including a first map area corresponding to a starting location of a vehicle, into a data-reading arrangement associated with the navigation device, wherein the data-reading arrangement is a data-media drive connected to the navigation device;
automatically transferring the navigation data to a memory of the navigation device;
after automatically transferring the navigation data to the memory, determining, at the navigation device, that the first data medium does not contain navigation data needed to reach the destination;
responsive to the determining, prompting the user to replace the first data medium with a second data medium containing the needed navigation data, including a second map area corresponding to the destination, wherein the second data medium does not contain data corresponding to the first map area;
after the first data medium is replaced with the second data medium, automatically transferring additional navigation data from the second data medium to the memory;
at the navigation device, responsive to the transferring of the additional navigation data, calculating a trip route from the first map area to the second map area, using the automatically transferred navigation data to calculate a portion of the trip route along the first map area, and using the additional navigation data to calculate a portion of the trip route along the second map area; and
outputting navigation instructions to the user based on the calculated trip route.

Abstract
Method for navigating a vehicle in a road system is provided, in which method data is read from a data-storage medium and automatically transferred to a memory of a navigation device after the data medium is inserted into a data-media drive associated with the navigation device. The transferred data remains available for vehicle navigation even after the data medium is removed from the data-media drive.

9. A method for performing a vehicle navigation along a road system using a navigation device, comprising:
-
transferring navigation data contained in a first data medium to a memory of the navigation device; calculating a trip route using the transferred navigation data; after calculating the trip route, locating, in the first data medium, additional navigation data corresponding to an area surrounding the trip route, wherein the navigation device determines the area surrounding the trip route narrowly in a vicinity of a starting point and a destination, relative to a portion of the area surrounding the trip route corresponding to a middle of the route; transferring the additional navigation data from the first data medium to the memory; outputting navigation instructions based on the calculated trip route; periodically determining whether the vehicle is located in the area surrounding the trip route; and responsive to determining that the vehicle is no longer in the area surrounding the trip route, re-calculating the trip route using new navigation data from the first data medium.
