Yes. It does.Does the MyLink support XM Traffic? The few dealers I have talked to say it does, and the XM website says it 'may' support it. This isn't Traffic Link (Fuel/Movies/etc), but the actual traffic with delays, accidents, etc.
I have the XM Traffic on what will be my trade-in and would love to not just have to dump it and use OnStar which I am not very fond of.
