NAVIGATION DEVICE AND METHOD
First Claim
1. A method of operating a navigation system, the navigation system including memory to store map data, including one or more base map data files;
- a display; and
a GPS signal reception and processing device by which a current location is determinable, and by which a basis is formed for navigation, route guidance, and map information display on the display, the method comprising;
correlating a current location of the navigation system with the stored map data to derive one or more map-specific parameters for the current location; and
comparing the derived one or more map-specific parameters with one or more of a motion-specific parameter, a vehicle-specific parameter, and the current location, to determine whether the one or more of the current location, motion-specific parameter and vehicle-specific parameter is permissible or appropriate for the derived one or more map-specific parameters; and
performing at least one secondary action in the event that it is determined that the one or more of the current location, motion specific parameter and vehicle-specific parameter and the derived one or more map-specific parameters are not permissible or appropriate for one another.

Abstract
A method of operating a PND or navigation system is described, together with a PND or navigation system for performing such a method. The PND or navigation system includes memory storing map data consisting of base map data files, a display, GPS signal reception and processing device, such together forming a basis for navigation, route guidance, and map information display. In at least one embodiment, the method includes correlating the current location with the map data to derive map-specific parameters for that location and comparing the map-specific parameters with a motion-specific parameter, a vehicle-specific parameter, or the current location to determine whether the current location, motion or vehicle-related characteristic is permissible or appropriate therefore; and in the event that the current location, motion, or vehicle-related characteristic and derived map-specific parameter are seemingly at odds with one another, performing at least one secondary action. The secondary action may include but is not limited to the issuing of an approve/reject prompt to the user, or the automatic creation, modification or deletion of a new or pre-existing correction.

13. A navigation system, comprising:
-
memory to store map data including one or more base map data files; a display; GPS signal reception and processing device by which a current location is determinable, and by which a basis is formed for navigation, route guidance, and map information display on said display; and a processor to correlate a current location of the navigation system with said stored map data to derive one or more map-specific parameters for the current location and to compares said derived one or more map-specific parameters with one or more of a motion-specific parameter, a vehicle-specific parameter, and the current location, to determine whether the current location, motion-specific parameter or vehicle-specific parameter is permissible or appropriate for the derived one or more map-specific parameters, and in the event that it is determined that the current location, motion-specific parameter, or vehicle-specific parameter and the derived one or more map-specific parameters are not permissible or appropriate for one another, to cause at least one secondary action to be performed. - View Dependent Claims (14, 18, 19)

16. A method of operating a navigation system, the navigation system including memory to store map data, including one or more base map data files;
- a display; and
a GPS signal reception and processing device by which a current location is determinable, and by which a basis is formed for navigation, route guidance, and map information display on the display,calculating a route between a current location and a destination entered or selected by a user; correlating the current location with said calculated route to determine whether or not the calculated route is being followed by the navigation device; and subsequently issuing, in the event that it is determined that the calculated route is not being followed by the navigation device at least one prompt to a user of the navigation device including a request to confirm that one or more restrictions or conditions prevail along a portion of the calculated route immediately following a point along said calculated route at which the navigation device determines that the calculated route is not being followed by the navigation device, and then automatically creating a new, or altering, qualifying, correcting or deleting a previously existing, map data correction including at least some location information identifying said portion of the calculated route and the one or more restrictions or conditions. - View Dependent Claims (17)
