PCMc----great information. Thank you. Prior to posting we did what you outlined above and saw the car had the free lifetime Premium Connectivity, but we couldn't find any information on how to activate the Traffic Visualization. We thought that it got disconnected somehow---maybe with the updates or when we re-booted or something. As a result, I decided to try posting on this Forum. And you came through for us! People like you are what makes this Forum so helpful---thank you. And thank you for your patience.
PCMc, your answers above are going to be a big help as we are going on a trip in two weeks, and we know that 3-5 areas will have traffic backups. Now we will be able to see on the screen just how bad things will be without having to use WAVES on my wife's phone. And, the super charger information you explained how to access will provide great piece of mind to both of us.
