Abstract
A system for providing an externally visible signal regarding a navigational instruction at a vehicle includes a navigation system, a navigation message sender, a navigation message receiver, and a display system. The navigation system generates and outputs turn-by-turn navigational directions within the vehicle to assist a driver of the vehicle in reaching a given destination location. The navigation message sender receives the turn-by-turn navigational directions and transmits them to the navigation message receiver. The navigation message receiver provides a navigational message to the display system for display in a manner visible outside the vehicle.
