Abstract:
1. A navigation device, comprising: a storage device, in the navigation device, to locally store vector-based map information; a processor, in the navigation device, configured to determine a route of travel based upon a current position of the navigation device within the locally stored vector-based map information and a destination position within the locally stored vector-based map information, the processor configured to determine at least one action point on the route of travel, the at least one action point being a point along the route of travel where more than one route action is available; and a display, in the navigation device, configured to display the current position in a graphical representation of the locally stored vector-based map information and to display the determined route of travel, the display being further configured to display additional information from the locally stored vector-based map information upon the processor determining that the at least one action point is within a threshold distance of the current position of the navigation device.
