CA 2228068
A method of enabling an on-board vehicle navigation system to compute a route from a current position of the vehicle to a desired destination is provided. A user of the navigation system in a vehicle utilizes a cellular telephone or any other wireless, two-way audio communications link to contact an operator in a remote communications center. The user informs the operator of his desired destination. The operator in the communications center accesses a computer database to determine the exact location of the desired destination in terms of latitude/longitude, street address, or other similar information. The operator then causes the information specifying the exact location to be transmitted from the communications center to the on-board vehicle navigation system over a data link. The on-board vehicle navigation system receives the location information and uses it to compute a route from the vehicle's current position to the desired destination.
