So I've had an iPhone 6 Plus for a few years and have never had a single issue synch it with my Fords audio system. Last week I bought a new 7 Plus and it disconnects every 5-10 minutes when on a call. I've tried cancelling the Bluetooth and reconnecting a number of times but the 7 will not stay connected. I use this phone for work and can't continue to use the 7... Anyone with any insight into why the 7 is useless compared to my old 6?
