I took delivery of the latest Auris sports tourer a month ago. I found the RDS-TMC info on the sat nav did not seem to be receiving traffic data, it would work fine when using an internet connection, on my previous auris and several prius version the TMC radio would show data, even without a route set up.  The dealer had the car back for a couple of days and said they would contact toyota and get back to me, Toyota wanted them to replace the sat nav, so the car was back to the dealer for a day
