Guys, I just bought a 2007 TL Type S. I've got XM Nav working with icons for traffic incidents but I don't think the traffic speeds are working right. Plus, every time I talk to XM, I get a run around and different stories each time. First, they said they'll resend a signal to the car....just turn to XM channel 1. Then I talked to a Nav dept. (I didn't even know they had a department for that) and they told me something different too. They said to turn to Channel 1 PLUS leave the nav screen on for 20 minutes !!!! Oh my gosh...20 minutes???? Has anyone got a real answer?
