1. A method of controlling a navigation system comprising:
- inputting an indication of a destination location to a mobile computer unit;
monitoring the current location of the mobile computer unit;
outputting a suggested route for reaching the destination location from the current location along a route selected on a predefined map, wherein the suggested route is determined by the mobile computer unit and takes into consideration traffic data stored on the mobile computer unit;
monitoring at the mobile computer unit, deviations from the suggested route;
building in the mobile computer unit, a repository of historical information about the deviations; and
using the historical information about the deviations in the mobile computer unit to improve the traffic data stored on the mobile computer unit.
