System and method of automatic destination selection

When a user enters, initializes, or otherwise starts using a navigation function, such as a navigation function on a mobile phone or a stand-alone device, a destination is automatically selected for route generation and production of a navigation output comprising one or more of a route to the pre-defined destination and an Estimated Time of Arrival (ETA). The destination is selected based on current proximity to a location that has a pre-defined destination associated with it. Such pre-defined destination usually is associated with the location by the user. A time of day criteria can also be imposed, such as requiring that the time of day either by in the morning or afternoon, a work day, or a holiday, or the opposite. In one concrete example, locations proximate a work place can be associated with home as a pre-defined destination, and vice versa. A time of day criteria can be imposed, such that even if proximate work and it is in the morning, a route and ETA to home will not be generated.
