When I bought my 2013 Ram and added my iphone4S I was getting a tone through my speakers when I received a text message. That only lasted about a month. Im wondering if I may have accidently done something to my settings on my phone that caused me to no longer get the tone through the speakers. I had the new update from Chrysler applied to my headunit last week but it did not fix the problem making me think it might be my settings on my phone. It comes up on my dash that I have a new text message but no tone. Anybody else having this issue?
