Abstract

Disclosed is a telematics system comprising a telematics terminal for storing complex intersection images and providing information related to a present position and a running direction by using the complex intersection images, and a telematics server for sharing ID codes of the complex intersection images stored in the telematics terminal with the telematics terminal and creating route data in response to a request from the telematics terminal, wherein the telematics server adds the ID codes of the complex intersection images to the route data when the route data include complex intersections and transmits the ID codes of the complex intersection images and the route data to the telematics terminal. The telematics system provides route information, which is easily recognized by users.
