<p>A navigation system includes a database of a plurality of roads, a position determining system, an input device, and a route determination system. A CPU samples user inputs and a counter keeps track of the number of occurrences of those user inputs which achieve a particular user desired result. The CPU identifies the user inputs which achieve a particular result and stores such inputs within a user input database maintained in a storage device. The CPU continues to store the user inputs which achieve a desired user result until a predetermined number of 'N' occurrences is reached. After reaching the 'N' number of occurrences, it has become apparent that this is not an infrequent inefficient input by the user. The CPU will then display a suggestion screen which provides a predetermined suggested input tailored to the prior inefficient user inputs.</p> |
