Navigation device and method

A navigation device comprising:

• a processor configured to generate a navigation map of a local environment;
• a display controllable by said processor and configured to display said navigation map;
• and
• an indicator generation module for generating an indicator for one or more marked locations outside of a displayed navigation map,
• said processor being responsive to said indicator generation module to control said display to display said navigation map and display of any said generated indicators on said navigation map;
• and
• said processor also being responsive to changes in direction by the navigation device, wherein upon a change in direction by the navigation device, the processor changes a position of any said generated indicators displayed on said navigation map.

The navigation device of claim 23, wherein the indicator generation module is configured to populate each indicator with at least one of a plurality of information elements comprising:

• a distance element indicating a distance between a reference point on said displayed navigation map and the marked location;
• a direction element indicating a direction of a location for the marked location with respect to a center of the navigation map;
• a manuever element indicating a type a manuever to occur at a waypoint;
• and
• an icon corresponding to the marked location.

The navigation device of claim 23, further comprising:

• an antenna;
• and
• a receiver for receiving data signals via said antenna;
• wherein said processor is configured to determine from said received data signals, a current location of said navigation device and the map generated by the processor is of a local environment that includes said current position, and
• wherein said processor is configured to periodically repeat the determination of said current position and to generate said new map if a determined location for said navigation device should differ from said previously determined current position.

A method of displaying a navigation map on a display of a navigation device, the method comprising:

• generating, by at least one processor, a navigation map of a local environment;
• determining, by the at least one processor, whether there are any marked locations outside of said local environment;
• generating, by the at least one processor, an indicator for display of one or more of said marked locations that are determined to be outside of said local environment;
• displaying, on said display of the navigation device, said navigation map and any of said indicators on said navigation map;
• and
• determining, by the at least one processor, a change in direction by the navigation device, and, upon a change in direction by the navigation device, changing a position of any said generated indicators displayed on said navigation map.

A non-transitory computer-readable medium having computer software stored thereon, said computer software comprising one or more software modules operable, when executed in an execution environment, to cause a processor to:

• generate a navigation map of a local environment;
• determine whether there are any marked locations outside of said local environment;
• generate an indicator for display of one or more of said marked locations that are determined to be outside of said local environment;
• display said navigation map and any of said indicators on said navigation map;
• and
• determine a change in direction by the navigation device, and, upon a change in direction by the navigation device, changing a position of any said generated indicators displayed on said navigation map.
