図データ記録媒体から読み出した道路地図上に表
示する車載用航法装置であつて、次に通過が予想
される交差点が立体交差であれば、その旨を車両
が当該交差点に差し掛かる前に、車室内表示する
立体交差表示手段を設けてなる車載用航法装置。 An in-vehicle navigation device that displays the estimated travel trajectory or estimated current location of a vehicle on a road map read out from a road map data recording medium, and if the next intersection expected to be passed is a grade-separated intersection, it will indicate that fact. An in-vehicle navigation device is provided with a grade separation display means that displays an indication inside the vehicle before the vehicle approaches the intersection.
