Abstract
In a navigation device assisting a driver of a vehicle to drive safely by presenting accurate information at the right time what is going on around his/her vehicle, an obstacle detection part detects any obstacle with the help of external information monitored by an external monitor part. By utilizing the vehicle'"'"'s current position detected by an input part and a position detection part, and map data stored in a map data storage part, a route selection part searches for a route to a destination. Based on thus found route, current position, map data, and the external information from the obstacle detection part, a guiding part performs route guidance to the destination. A map data arranging part refers to the map data, information from the obstacle detection part and the input part, and object model display information from the object model display information storage part, and arranges any applicable object model onto a map data space. A display accordingly displays guidance information together with the resulting map image.
