S5 Paired w/ My Ford Flex Just Fine, But...

[monicakm]

I just paired my S5 to my Ford Flex for the first time today. That went flawlessly. I've made it my default phone for the car. When I want to make a call, I push a button on the steering wheel and say "phone" and then the person I want to call. It's all done via the car, no interaction with my phone. When a call comes in, again, no interaction with my phone, Just touch "send" on the nav screen to connect. All talking and ringtones come thru the car's speakers. What I can't get it to do is use my phone's ring tone as the ONLY ring tone that comes thru car's speakers. I have it set to use my phone's ringer but instead, my phone rings using one ringtone and the car uses another. The text reading feature works too. Does anyone have any idea what I need to do (on the phone) for the the ringer to sound over the car's speakers?
Thanks
