PROBLEM TO BE SOLVED: To surely make a user exchange consumables who tends to be forgetful or has little knowledge about vehicles. SOLUTION: The on-vehicle navigation apparatus displays own vehicle position on a map screen at a display device 7 from the present position obtained by an own vehicle position-operating device 2 and map data read by a recording medium-reading device 4, thereby guiding the vehicle to run. The apparatus has a memory means 5 for storing an accumulated elapsed time and an accumulated run distance for each warning item, and a comparing means 1 for comparing the stored accumulated passed time and accumulated run distance with respective set values. The display device 7 or a sound output device 8 issues warnings, when the stored accumulated elapsed time or accumulated run distance exceeds respective set values. |
