  • receiving traffic information through a wireless communication device;

    identifying locations of all of traffic incidents in a coverage area which includes a current position of a user of the navigation system and a calculated route to a destination where the coverage area is an area which is sufficiently large for encompassing possible routes to the destination other than the calculated route;

    displaying a list of the traffic incidents that exist only on the calculated route to the destination on the navigation system;

    selecting a traffic incident displayed on the navigation system to review a live image of the traffic incident downloaded through a wireless communication;

    selecting two or more traffic incidents to be avoided on a route to the destination from the traffic incident list which shows the traffic incidents that exist on the calculated route to the destination; and

    instructing the navigation system to calculate and produce a new route to the destination which does not have the selected traffic incident and displaying the new calculated route on the navigation system;

    wherein the traffic incidents are listed on the traffic incident list by two or more different icons representing predefined types of traffic incident.
