Abstract:
A technique of detecting a speed detection of a vehicle using a geographic database (200, 322, 326, 508, 510) of a navigation system (300, 502) has been provided, which obtains a current position of the vehicle (404) and at least one predefined characteristic (418) relating to the current position of the vehicle from the geographic database, sets (420(1)) a sensitivity level to detect a speed detection of the vehicle based, at least in part, on the at least one predefined characteristic.
