A vehicular scalable integrated control system includes a plurality of cameras, a vehicular scalable integrated control unit, and a display screen for displaying video information to a driver of the vehicle. Visual image data captured by the cameras is processed by an image processor to detect objects in the fields of view of the cameras. The control unit determines a current geographical location of the vehicle and accommodates downloading of applications, which may include a tour guide application, with the tour guide application providing information associated with various geographical locations of a selected tour area. The control unit, responsive to a determination that the current geographical location of the vehicle is at a location identified in the tour guide application for the selected tour area, controls the display screen to display information associated with the identified location of the tour guide application and the current geographical location of the vehicle.
