Is there a way to manually detour around traffic? I know that when I am in an area with NavTraffic and there is traffic ahead it asks me if I want to detour around it? But many times I am not in a coverage area, or an accident happened and the incident report is not relayed.

I know you can choose alternate routes, if they are availble, when chooseing to accept a new route. You know that page that asks you is the route OK, by picking mulitple you can pick an alterate.

Otherwise I don't know if it has a option to manually pick another route around traffic.

I'm just getting to know mine so there may be other ways.
