Abstract: In a first embodiment, the present invention permits an occupant of a vehicle to enter a message, with a handheld communications device having Wide Area Network (WAN) capability, and to have the message externally displayed for reading by persons who are not occupants of the vehicle. The message is displayed by an on-board telematic unit. In addition to a display, the telematic unit can contain a variety of sensors and/or effectors. Sensor readings from a vehicle X can be updated, approximately continuously, in a record (of a vehicle-oriented database) that stores information particular to vehicle X. The vehicle-oriented database can provide an open Application Programming Interface, in order to serve as a platform for a wide variety of application programs (or Apps). An App is presented that permits a person to contact the occupants, of a vehicle X, based only upon information from vehicle X's license plate.
