A travel guide device includes a GPS receiver for determining a present location. Access to a database of points-of-interest, indexed by GPS location, is provided to permit timely presentation of audio narration or visual display of information relevant to the point-of-interest. A running, general area narrative and/or display may alternatively be provided. The travel guide device may provide educational and entertaining games, including interactive competitive games, relating to the points-of-interest and general area narratives. A navigation function includes automatic, intelligent collection of waypoints and general directions without stored, detailed maps of an area for which directions are being provided. Waypoint collections may be employed to document a route travel, to retrace the route, or for other purposes. A directory of locations such as restaurants, filling stations, and the like may be accessed by the travel guide device to determine GPS coordinates for a desired destination for general directions navigation. Communication facilities integrated into the travel guide device provide optional communications services, such as downloading a local directory for an area being entered.
