From what I can see (haven't got my car yet) there are two options for traffic data on the MMI with connect.
TMC based (i.e. via Classic FM, the old skool way)
Inrix/Google based Traffic received by the Simcard/data plan
Any thoughts on which one is more accurate or gives better data??
I've had a look at the Inrix app on the iPhone and it's nothing special, but that doesn't mean it is using the same data as the Audi implementation.
