SYSTEM AND METHOD FOR REDUCING THE AMOUNT OF REPETITIVE DATA SENT BY A SERVER TO A CLIENT FOR VEHICLE NAVIGATION A system and method for reducing the amount of repetitive data sent by a server to a client for vehicle navigation. The system includes a computer-based vehicle unit located in a vehicle, a gateway configured to wirelessly send and receive trip informatio n to and from the vehicle unit, and a computer-based server in communication with the gateway over a network. The vehicle unit wirelessly receives signals from a computer-based server that includes the desired navigation information in packet form. The vehicle unit includes a user interface component that presents the received navigation information and records user requests. The server processes the requests, generates a trip plan according to the navigation information and sends the generated trip plan back to the vehicle unit via a gateway when a request has been completed. -14-
