Publication number: 20090240429Abstract: A method for route planning for use with a vehicle navigation system. The method includes the steps of inputting a route origin and route destination on a computer separate from the navigation system, such as a PC. The user also inputs activities or points of interest. The computer then searches a point of interest database which matches the activities inputted by the user and calculates a preferred route from the origin and to the route destination. The preferred route, together with data relating to the points of activity, are then wirelessly transmitted to the navigation system for subsequent display on the navigation system screen.Type: ApplicationFiled: March 19, 2008Publication date: September 24, 2009Applicant: Xanavi informatics CorporationInventors: Katsuaki Tanaka, Deepak Ramaswamy
