Abstract: A method and navigation device are disclosed which allow for switching the display of map information, depending on the current position and the availability of relatively more detailed map information. In one embodiment, the method includes receiving information of a current position and displaying map information including the current position on a navigation device; determining relative map information coverage for the current position; and switching the displayed map information to display map information of relatively more detailed coverage of the current position, upon determining that map information of relatively more detailed coverage of the current position is displayable. The method may include determining a travel route based upon a travel destination input into a navigation device and determining whether or not, based upon the current position information, travel along the route enters a region wherein the relatively more detailed map information is displayable.

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 of integrating audio features using a navigation device is disclosed herein, along with a navigation device itself. For example, in one embodiment the method may include receiving an interruption signal for interruption of audio playback, determining to interrupt audio playback using the navigation device in response to receipt of the interruption signal, and storing an interruption state of audio playback upon determining to interrupt the audio playback.

Abstract: A method of displaying navigation information and A navigation device comprising a receiver to receive traffic information, whereas the device is programmed with a map database and software that enables to display a current position of the device on a road navigation map, the device is further programmed to be able to display a status bar providing information about a planned route, whereas the user can plan a first route by inputting a first position and inputting a second position and store said first position and said second position, the user can initiate a displaying of received traffic information assigned to said first route between said stored first position and said stored second position independent from the current position, and after displaying of received traffic information assigned to said first route between said stored first position and said stored second position a second route is calculated between the current position and a destination.

Abstract: A method and device are disclosed for providing a navigation device particularly suited for walking routes. In one embodiment, the method includes determining, in a navigation device, a number of maps for traveling along a route based upon an initial position and an input end position; inputting the end position; and displaying a map on the navigation device and prompting sequential display of the determined number of maps for traveling along the route from the initial position to the input end position.

Abstract: A method and navigation device are disclosed for map switching. In one embodiment, the method includes receiving information of a current position and displaying map information including the current position on a navigation device; determining relative map information coverage for the current position; and switching the displayed map information to display map information of relatively more detailed coverage of the current position, upon determining that map information of relatively more detailed coverage of the current position is displayable.

Abstract: A method and device are disclosed for storing and utilizing a location at which a navigation device was last connected to a vehicle and/or was disconnected from a vehicle. In one embodiment, the method includes storing a positional location at which a navigation device was last connected to a vehicle; and determining a route to the vehicle based upon a current location of the navigation device and the stored positional location at which the navigation device was last connected to the vehicle. In another embodiment, the method includes storing a positional location of a navigation device upon disconnection from a vehicle; and determining a route to the vehicle based upon a current location of the navigation device and the stored positional location at which the navigation device was disconnected from the vehicle.

Abstract: A method and device are disclosed for activating information on a navigation device. In one embodiment, the method includes prompting selection of information for receipt from a remote server, connected to the navigation device via an internet connection; requesting, upon selected information requiring activation, input of further information before activating the selected information; and activating the selected information on the navigation device upon receipt of the requested information to activate. In one embodiment, the navigation device includes an integrated input and display device to prompt selection of information for receipt from a remote server, connected to the navigation device via an internet connection. The integrated input and display device is further used to request, upon selected information requiring activation, input of further information before activating the selected information.

Abstract: Methods, servers, and navigation devices are disclosed. An embodiment of a method includes receiving information from a navigation device at a server, the navigation device being connected to the server via a network connection established at least one of through a mobile device and via mobile phone technology within the navigation device; and pushing information relating to the received information, via at least one push channel over a network connection, from the server to a plurality of navigation devices connected to the server.
