Abstract
A navigation device comprises an itinerary preparation and management system. The device includes a memory for storing itinerary data including data representative of a destination and a time constraint, such as a deadline, earliest time, or range of times during which the user wants to arrive at the destination. The navigation device also includes a display for displaying the itinerary, a position detection system for detecting positional information associated with the navigation device, and a processor programmable to correlate the positional information with the itinerary data and detect an inability to satisfy the time constraint. The navigation device has access to alternative destinations and is able to determine whether one of the alternative destinations will satisfy the time constraint. If so, the navigation device provides the user with an opportunity to replace the destination with the alternative destination.
