Abstract
A vehicle navigation system and method. The system includes a unit located in a vehicle and coupled to a first network, a traffic information center coupled to a second network, and a server coupled to the first and second networks. A trip plan is generated according to navigation information, vehicle coordinates and trip request information received from the unit, and road information received from the traffic information center. The trip plan is sent to the unit for presentation. The trip plan includes trip overview information and voice prompts associated with one or more landmarks. A trip plan may be a tourist trip plan.
