Abstract: A navigation apparatus includes an image recording device for recording image data and a processing resource configured to receive an incident signal indicative of the occurrence of an incident and to perform an image data processing operation in response to the incident signal.

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.

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 and supplemental corrective data files. In at least one embodiment, the method includes correlating the current location with the map data, and in the event that the current location and derived map data are seemingly at odds with one another, performing at least one secondary action. In at least one embodiment, the secondary action may be the issuing of an approve/reject prompt to the user, or the automatic creation, modification or deletion of a new or pre-existing correction. In a further aspect, at least one embodiment of the invention also provides for a PND or navigation system storing an indication of a home location, and prompting a user to visit nearby locations for which corrections exist, followed by prompted or automatic confirmation or rejection thereof.

Abstract: A method of correcting map data stored on a portable navigation device or navigation system is described, together with an appropriately enabled device or navigation system. A computer program enabling the method is also described. The method includes the steps of displaying map data on a PND or navigation system during a navigation or free-driving mode, and is characterized in that at least one of a plurality of user-selectable graphical indicators is displayed together with said map data adjacent or overlaid on the particular thoroughfare along which the device is currently traveling, the indicator graphically representing a travel restriction pertinent to one of either the current thoroughfare or a subsequent thoroughfare occurring after a thoroughfare intersection towards which the current thoroughfare leads.

Abstract: A method and a navigation device are disclosed for sharing at least one location message with at least one other device. The navigation device includes a receiver to determine a signal strength of a traffic message channel at a location, a memory to store information representing the signal strength of a traffic message channel, and at least one processor to correlate the information stored in memory to compile a traffic message channel resource and select a traffic message channel based on the traffic message channel resource and a location associated with a navigation device. The method includes determining a signal strength of a traffic message channel at a location, storing information representing the signal strength of a traffic message channel, correlating the information stored in memory to compile a traffic message channel resource, and selecting a traffic message channel based on the traffic message channel resource and a location associated with a navigation device.

Abstract: A method and a navigation device are disclosed for sharing at least one location message with at least one other device. The navigation device includes a receiver to receive multiple traffic message channels, an input device to receive a user input indicating a frequency, and a processor to select a traffic message channel based on a signal strength, starting with the indicated frequency. The method includes receiving multiple traffic message channels, receiving a user input indicating a frequency, and a selecting a traffic message channel based on a planned route, starting with the indicated frequency.

Abstract: A method and a navigation device are disclosed for displaying a rich content document. The navigation device includes an input device to receive an input for selecting a rich content document and a display device to display the rich content document. The rich content document is at least one of a document stored in memory associated with the navigation device and a document acquired via a network connection. The method includes receiving an input for selecting a rich content document and displaying the rich content document on a navigation device display. The rich content document is at least one of a document stored in memory associated with the navigation device and a document acquired via a network connection.
