ABSTRACT:
A method and apparatus for providing navigation information including a simplified location display. The mobile unit includes a GPS position determination system including a GPS antenna, a GPS receiver, and a GPS processor. The system also includes a microprocessor and a database storage device. A map database is stored in the database storage device. In operation, the simplified location display system continually displays the travel path and location along the travel path that corresponds to the current location. The user may select optional displays which include the next cross street in the direction of travel, the last cross street in the direction of travel, the next parallel cross street to the right from the direction of travel, and the next parallel cross street to the left from the direction of travel. The user may also select subsequent pathway identification labels so as to identify subsequent streets either in the direction of travel, behind the direction of travel, and to the right and the left of the direction of travel. Other optional displays include the display of current location and special-use information. Special use information includes out of region alarms, distance and time to go to edge of region, and near perimeter warnings. Alternatively, optional displays may be displayed as grid locations instead of spelling out the complete street or highway names.
