1. A system for providing an externally visible signal regarding a navigational instruction at a vehicle, the system comprising: a navigation system for generating and outputting turn-by-turn navigational directions within the vehicle to assist a driver of the vehicle in reaching a given destination location; a navigation message sender for receiving turn-by-turn navigational directions from the navigation system and transmitting corresponding navigational messages; a navigation message receiver for receiving the navigational messages from the navigation message sender; and a display system for receiving the navigational messages from the navigation message receiver and in response displaying, a directional message in a manner visible outside the vehicle, a directional message based on the navigational messages; wherein the navigation message receiver is linked to a user signaling interface; wherein the user signaling interface includes at least one of a user-actuated lever and a user-actuated button for causing a turn indication to be display by the vehicle; and wherein the navigation message receiver is configured to receive a turn signal from the user signaling interface, to determine whether the received turn signal is consistent with a current received navigational message, and to provide the current navigational message to the display system only in the case that the received turn signal is consistent with the current received navigational message.
