I just bought a Go 720. One of the primary reasons I bought this unit was for the real-time traffic. I drive from San Diego to LA quite often and figured this would be a big help. But I'm disappointed to see that the Tom Tom traffic service doesn't work with Verizon because Verizon has locked it down supposedly. I don't quite understand that since it's just data, and if I have the data feature enabled on my Razr, how would Tom Tom know the difference? Anyway, my question is about the external rds-tmc receiver. It sure seems like the Tom Tom traffic service is better from what I read, and a couple reviews I read on the rds-tmc receiver were not favorable. Have any of you out there used the rds-tmc receiver, especially in the So Cal area? If so, did it help route you around traffic? Was it accurate? I've got to say one thing I liked about the Garmin Nuvi is that the traffic antenna was built into the unit. I'm disappointed that I now have to buy an external antenna and have one more thing on my windshield to get this to work. Seems like a brand-new model like the Go 720 would have a better option, like Garmin's built-in antenna.
