In my 2014 CTS the traffic conditions and colors only involve Interstate highways. But I have driven 2015 models for BMW and Nissan and their traffic covers more roads - all major roads in the area - much better coverage than simply Interstates. Do 2015 Cadillac models also work like that, or do they still use the old system that only covers Interstate highways?? And if it does cover the same added coverage that other 2015 models have, can we update our 2014 system to get that added coverage?? My dealer was unaware of any updates, but XM support told me an update was available for my 2014 CTS!!
Thanks.
Thanks.
