Abstract
A method for selecting a destination in a vehicle navigation system is described. A plurality of options are provided for designating the destination in the system's user interface. A first option employs at least one street name to designate the destination. In response to selection of the first option, a list of cities is provided for display in the user interface. The list of cities includes a first plurality of cities for which no street names are available for display and a second plurality of cities for which only a few street names are available for display. In response to selection of one of the first plurality of cities from the list of cities, a first location associated with the selected city in the map database is selected as the destination. In response to selection of one of the second plurality of cities from the list of cities, an enhanced street name list is presented which includes the names of the few street names as well as an entry corresponding to a specific location in the selected city.
