I am wondering if anyone has experienced any problems with the XM NavTraffic service. About once a month I drive round trip from Baltimore to Long Island. Routinely I can drive long stretches on I-95 and the NJ Turnpike and even 278 in NY, and I don't have any traffic flow information. I would think at a minimum those would be several roads that would be covered. I am not sure if the problem is with the SiriusXM service or with my unit. My GPS screen says it is receiving traffic information but if I try to look at traffic information on route for instance, it says it has not traffic information for my route. Thought I would ask before I start making phone calls.
