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. ## Claims ### Claim 1 A vehicular navigation system updating system for updating vehicular navigation systems in vehicles, comprising: at least one condition detector that automatically detects presence of an object or condition at a specific location and for which presence of the object or condition at the specific location affects movement of vehicles on a roadway, said at least one condition detector being configured to detect the presence of the object or condition at the specific location without requiring manual entry of data about the object or condition at the specific location, said at least one condition detector being situated on a vehicle;
