Abstract
A method of providing navigation information by recalculating a navigation route is used in a global positioning device. The method reads an original navigation route first. If another new navigation route can be read again, it shows that the global positioning device is deviated from the original navigation route, and route data of the original navigation route and the new navigation route are compared to generate a comparing information such as an overlapped position of the two navigation routes, and the time or distance required to return to the original new navigation route from the new navigation route and display the comparing information on the global positioning device to remind the users. The present invention can greatly reduce the tension of a user who is not familiar with the routes and road conditions.
