I have a 2015 Limited & an IPhone 6 I'm suddenly having issues with text messages not playing. It has always been sort of haphazard as to whether or not they display while driving. Now they do not display until I am stopped - understandably a safety issue. But until recently, the messages would play automatically - now they won't play at all. I've checked for a setting on my phone - not finding anything. Is there a setting on the vehicle? Thanks!
