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 (e.g., an Estimated Time of Arrival (ETA) at the destination). 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 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.

When a user specifies a road that he / she wants to pass through, a guiding route generation device generates a guiding route that passes through the specified road up to a destination. A guiding route (37) generated based on waypoints specified is stored in a storage means (15) of the guiding route generation device. A display means (11) displays the guiding route (37) along with roads in the periphery. The guiding route generation device specifies a certain road as the specified pass-through road from among the roads displayed along with the guiding route (37), and further, finds and determines whether there are crossings and the number of the crossings between the specified pass-through road and the guiding route (37). When there is no crossing, the guiding route generation device generates two routes between the specified pass-through road and the guiding route (37) and extends the specified pass-through road to generate a user-specified road. When there is one crossing, the guiding route generation device generates one route between the specified pass-through road and the guiding route (37) and extends the specified pass-through road to generate a user-specified road. A user-specified road and the guiding route (37) are connected to generate a renewed guiding route.
