So it is out on 2007 vehicles, and one of the listed is the X5 which is coming with I-Drive in 2007 right? So do I have to have the new car with I-Drive to have TMC (Traffic Message Channel)? In Europe they have had this technology available for a while now... Does anyone here know if it works with a non I-Drive setup?

As far as I have researched it looked like I would need a new radio module to make this happen, i didn't even think about I-Drive. Your source says the upgrade will be free, makes me wonder what all is involved and what cars it will pertain to.
