An apparatus and method for a navigation system including an information center and a mobile terminal is disclosed. The information center stores node image information on topographic features of a node. The node image information includes partial image information according to a direction of movement of the mobile terminal. The information center includes a database for storing a node message having the partial image information and a database for storing map data. The information center generates the node message for guiding the next node point whenever the mobile terminal reaches a node point, and transmits partial image information of the node image information corresponding to the direction of movement of the mobile terminal. The mobile terminal displays the image information of the node received at each node point and confirms a movement path.
