Abstract
Abstract A road displaying method in a navigation device permits the normal and convenient display of a road name to the user, even though the next road to be traveled or approached is unnamed. In a navigation device operable to guide a vehicle in accordance with a searched guidance route and to display a road name of a next road to be traveled, in a case where the next road to be traveled is not named, a first available road having a road name is determined from the roads included in the guidance route beyond the next road, and the road name of the determined road is displayed.
