Abstract
A navigation system uses a geographic database to determine a solution route to a destination and provides detailed maneuvering guidance for following the solution route. In addition, the navigation system includes a preview function that provides a summary of the solution route prior to providing the detailed maneuvering guidance for following the solution route. The preview function is included in the programming of the navigation system. The preview function uses a feature incorporated in the geographic database wherein the portion of the geographic database used by the navigation system when determining a solution route includes references to another portion of the database that includes the actual text of the names of the roads represented thereby. As the navigation system uses the data in the geographic database to determine the solution route, data representing the roads in the solution route are saved, including the references to the other portion of the geographic database that includes the actual text of the names of the roads. After the solution route is determined, the preview function evaluates the data representing the roads in the solution route and provides a list o…
