Does the radio in Model S have RDS or more specific TA (trafic announcement) ? Radio Data System - Wikipedia, the free encyclopedia Every car I've owned have had this, and I have been very happy by this safety feature. I belive RDS is also used in the US, but don't know if it is commonly used. Here in europe it is commonly - even in a cheap cars. anyone know anything about RDS is available now or in the future for the model S ?
