Anyone with a US-spec 2008 or even better a 2009 LCI 3-series have RTTI working?

I've now heard from someone that RTTI apparently gets info from BMW Assist (which I would take to mean via the GSM link) rather than RDS/TMC. That doesn't sound right to me, but I haven't seen any BMW tech info on the functioning of the new system. Also, it appears that RTTI works in the US even before you enable BMW Assist, which suggests its independent (although BMW Assist could still be RX/TX info for auxiliary svcs without needing to be activated).
