If you want to avoid getting stuck in traffic (well, at least know about it and try to avoid getting stuck) you might be interested in this Real-time traffic kit from Delphi. The kit works with the Nav200 (and other navigators from Delphi) and can give you a route to avoid traffic jams and hazardous road conditions in real time. Unlike other traffic services the service is available for a one-time cost with no additional activation, monthly subscription or renewal fees.
