Method and apparatus providing supplementary navigation data to be used with a vehicular navigation system. The supplementary navigation data can be superimposed over primary navigation data on a navigation system display or can be presented as a split-screen display. The supplementary navigation data may contain information such as locations of local facilities, local road information, types of local facilities. The supplementary navigation data is received by the vehicle when the vehicle is coupled to a station, such as a battery recharging or a refueling station, and is transmitted to the navigation system. An on-board controller can store the data and / or display the data. The navigation system could use the supplementary data to determine routes or locations for specific local facilities selected by the user. In an interactive or two-way communications system, the user can select predetermined types of supplementary data to be received. The supplementary navigation data is preferably transmitted to the navigation system at a local vehicle station, such as a refueling station, a vehicle rest stop, a vehicle tourist center, etc. Position update information can also be entered for resetting or recalibrating an internally maintained vehicle position.
