  • Publication number: 20090119003
    Abstract: A navigation system provides guidance for performing a U-turn. The navigation system includes a processing unit, which acquires guidance route information and road information to determine whether the guidance route requires a turning around in a divided two-lane road. If a turning around is required, the processing unit specifies an extension distance of a connection road of the divided two-lane road. U-turn guidance is provided if the extension distance is at or below a predetermined length, or otherwise, to guidance is provided to prompt a double turn.
