Automobile navigation system using remote download of data
First Claim
1. A method of enabling an on-board navigation system in a vehicle to compute a route from a current position of the vehicle to a desired destination, the method comprising the steps of:
- receiving a voice transmission from a user, the voice transmission including information identifying the desired destination;
accessing a destination database to determine the location of the desired destination based on the information identifying the desired destination; and
sending a data transmission to the on-board navigation system, the data transmission including information specifying the location of the desired destination and secondary information, the secondary information including crime rate information, such that the information specifying the location of the desired destination and the secondary information are usable by the on-board vehicle navigation system to compute the route from the current position of the vehicle to the desired destination.

Abstract
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.
