Abstract
Abstract To provide a route guiding explanation device capable of adding or changing route information data or the like by general users without requiring any CPU of high-level function and any large number of memories. A destination absolute position storing portion stores latitude and longitude information of a destination converted by a destination absolute position converting portion. A present location neighboring landmark storing portion selects and stores a landmark name which is a most nearest to the latitude and longitude information of the present location absolute position storing portion. A destination neighboring landmark storing portion selects and stores the landmark name which is a most nearest to the latitude and longitude information of the destination absolute position storing portion. A landmark section travel explanation renewing portion regards a value of the present location neighboring landmark storing portion as a starting point landmark and the value of the destination neighboring landmark storing portion as a destination landmark and takes out the explanations from the landmark section travel explanation storing portion and renews the explanations for a driver.
