PURPOSE: To offer a route according to the operator's desire. CONSTITUTION: When an operator sets a destination by using an input section 16 or a voice input section 18, a navigation operation section 11 outputs one or more routes that are capable of reaching the destination from a current position which is detected by a current position detection section 13 by utilizing an indication section 17 or a sound output section 19. When the operator inputs a selection condition of the route (for example, to avoid a traffic jam, to arrive in a short time, to reduce a cost, etc.) by a voice via the voice input section 18, the navigation operation section 11 determines a recommendable route according to the input selection condition of the route by referring to a toll table of a toll road or route selection data 125 such as information of kinds of automobile ways and the like and outputs the recommendable route by utilizing the indication section 17 or the sound output section 19. |
