Photos: GPS traffic kit shows the way

The Nav200 from Delphi is one of several portable GPS systems on the market that now come with optional real-time traffic services that can reroute drivers around accidents, congested roadways or construction zones. The drawbacks: the kit costs extra--but in Delphi's case, it's a flat fee of $200 instead of an annual or monthly fee like others. Also, excess wires snake over the dashboard and windshield.
