Abstract

The invention provides an on-vehicle navigation system, route guide method, and computer-readable recording medium capable of setting an optimum guide point corresponding to proposed actions set as destinations or way points, and performing route guidance based on the setting. The on-vehicle navigation system includes a function of searching for a guide route leading to a set destination or the like and displaying the searched guide route on a screen of a display to guide the vehicle. The route guide method includes: registering information organized in a list form in a storage means, in which each of the places prepared as candidates for destinations or the like is associated in advance with proposed actions at the place; when a destination or the like is selected, extracting the information on the proposed actions at the place to display it in a list form on the screen of the display; when any of the proposed actions is selected, referring to a map database to search for a guide point corresponding to the selected proposed action; and setting the searched guide point as the destination or the like.
