A system and method of displaying position information including an image in a navigation system are disclosed. The navigation system has an information center and a mobile terminal. The information center includes a database for storing a node message with node image information about the geographical features of a node and a database for storing map data. The node image information is divided into image segments corresponding to directions. The information center sets a route according to a current position and a destination of the mobile terminal, generates map data including the route and nodes in the route, and transmits it to the mobile terminal. The mobile terminal selects nodes for which to receive node messages in the map data. The information center transmits a node message for the next node each time the mobile terminal reaches each of the selected nodes. The mobile terminal reproduces the node message.
