Vehicular navigation system updating system includes condition detectors that detect presence of an object or condition potentially interfering with movement of vehicles on a roadway, each condition detector being located on or alongside the roadway or in a vehicle. A signal, data or information about the detected presence of the object or condition is transmitted to a remote site at which a processor generates an update for a map based on the detected presence of the object or condition and directs communication of the map update to vehicles in a vicinity of a location at which the condition detector detected the presence of the object or condition. The vehicular navigation system of each vehicle uses the map with the map update to display or otherwise indicate the presence of the object or condition. Another map update is generated when the absence of the object or condition is determined.
