1. A vehicle navigation method comprising:
- initiating a trip request, including trip request information;
determining vehicle coordinates;
sending vehicle coordinates and the entered trip request information to a server over a network;
retrieving at the server road information based on the vehicle coordination and entered trip request information from an information center over a network connection;
generating a trip plan according to navigation information stored in a memory associated with the server, the vehicle coordinates, the trip request information, and the retrieved road information, wherein the generated trip plan includes a table of locations of the trip plan with associated navigation prompts;
sending the generated trip plan table to the vehicle over the network;
comparing present vehicle coordinates to the trip plan table; and
if, according to the comparison, the vehicle coordinates are within a threshold value from a location in the table, presenting the navigation prompt associated with the location in the table that is within the threshold value of the vehicle'"'"'s location.

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.
