How well does TomTom Traffic compare to Navigon's Traffic? Navigon's traffic does not function well at all here in Columbus, OH... I end up using INRIX's traffic app before work each morning to check for accidents.. Is TomTom traffic better than Navigon's? If so, why? Looking for insight into those of you who have both, or at least anyone who can speak to the taffic function in TomTom being on par with current accidents and rerouting properly.
