A vehicle navigation system includes a base and a handheld device which is portable relative to the base and dockable to the base. The handheld device includes a GPS receiver, display and user input devices and provides limited navigation capability when detached from the base. The base includes additional databases and navigation sensors which provide a full function navigation system when the handheld device is docked to the base station, including turn-by-turn navigation.
