I doubt that you will ever see a green TMC logo in the US. This function relies on the car receiving a European "Traffic Alert" signal from any radio station supporting "TP" (Traffic Programmes) tuned in on your car. Even if you are in Europe, if you have no pre-programmed radio station that supports TP, you will always see a RED TMC logo. Furthermore, the TMC function gives no warnings (even though it may be GREEN) unless you have activated a mapping route & are using it.
