Prior to IOS 9 my 6 plus worked perfectly in my car. ( 2015 VW Passat -hold the emission jokes for now). After IOS 9 the phone still registers and connects, and plays media, but when a call comes in, it goes directly to the phone, not the car system. I have de-paired, re-set network settings, re-set car settings and it still happens. I am not going to go crazy since I will be turning in the 6 Plus on Friday and getting a 6S Plus. I will update this post at that time.
