  • Patent number: 6157890
    Abstract: A navigational system particularly adapted for use with small open vehicles such as a motorcycle. The navigational system includes a display which displays, in addition to vehicle speed and distance traveled, navigational information as to points along a pre-selected course of travel and the distance and turning direction to reach each successive point. The operator may also insert information about each point, such as observations about the point as the name of the point. The display switches from providing a first display condition that provides the travel information and a second condition that permits the insertion of data into the system. The insertion display is not enabled unless the vehicle is in a standing condition.
