Claim One:
1. A navigation device, comprising: a mapping module arranged to determine an overall day's route including each of a plurality of separate trips to different ending locations, each of said plurality of separate trips being separated in time over a day; a database to maintain said different ending locations, and to determine an estimated total travel time of traversal for said overall day's route between a beginning geographic location of a first one of said plurality of separate trips, and an ending geographic location of a last one of said plurality of separate trips, based on an average of real time sampling of traffic patterns over an extended period of time, mapping data, and a future start time for traversing said overall day's route; a graphical departure time control arranged to modify said future start time for said overall day's route; and a display arranged to prompt a best time to depart on said overall day's route based on said average of real time sampling of traffic patterns over said extended period of time; wherein said mapping module is arranged to re-determine said estimated total travel time of traversal for said overall day's route, and update a map viewing area with future predictive traffic condition information, in response to movement of said graphical departure time control.
