Route guiding method in a navigation system using a wireless network

A route guiding method in a navigation system comprising an information center including a map database, a navigation terminal located within a moveable object including a mobile terminal, wirelessly connected to a wireless network, and an ITS (Intelligent Transportation System) terminal with a GPS (Global Positioning System) device for detecting a current location of the moveable object, and the wireless network for connecting the information center and the navigation terminal wirelessly, the method comprising the steps of:

• receiving route guidance data by which the moveable object is guided to a destination via a plurality of node points in an optimum route at the navigation terminal from the information center;
• and
• displaying route information about some of the node points in text if a user requests a preview of the optimum route, and displaying the preview information sequentially.

• receiving route guidance data by which the moveable object is guided to a destination via a plurality of node points in an optimum route at the navigation terminal from the information center;
• and
• generating preview information about each of the node points based on the route guidance data if a user requests a preview of the optimum route, and displaying the preview information sequentially.
