Abstract (en)
[origin: WO9731241A1] A vehicle navigation system (10) utilizing a wireless communications medium (74) for transmitting present position (77) and destination position (75) data to a central processing means (14) for generating a route. The central processing means generates a series of turn-by-turn routing vectors (82-87) comprising the route. The wireless communications medium transmits the turn-by-turn routing vectors to the vehicle for display either audibly or visually or both to the vehicle operator (34). A vehicle identification means can be used for updating the routing vectors upon subsequent transmissions.
