Abstract

Abstract A navigation unit which, when a destination is input, outputs guide data for arriving at the destination, and which comprises an input unit (1) for inputting destination, a storage unit (4) for storing guide data and destination data, and a display unit (3) for outputting the guide data and input data from the input unit, wherein said destination data include regional names and data related to the regions (10, 11, 12, 13, 14,15,16,17,18), and data related to the region are obtained when the regional name is input through the input unit. When the name of a prefecture, a city or a town is selected in which the destination is not specified, a path search routine is executed by the input of the prefecture, city or town name in order to search the list of prefecture names, that of city names and that of town names successively, and to set the intersection of the destination based on the addresses stored in the list of intersections and the list of characteristic marks. Even when the destination cannot be specified, therefore, a particular destination can be called from the ambiguous destination, e.g., a representative intersection or a representative mark is called to navigate the driver toward the destination.
