The SYNC in my 2016 Fiesta suddenly stopped working last weekend for no apparent reason. It was working fine, I got out of the car to eat breakfast, and when I got back in it was no longer working. My boyfriend and I tried all the trouble-shooting techniques we could find (Master Reset, SYNC Reboot, pulling and plugging in the SYNC fuse, and disconnecting/reconnecting the battery) and nothing fixed the issue. The strange thing is, we were able to connect my phone to the car still and make outgoing phone calls using Bluetooth. The command button on the steering wheel worked when you press the PHONE button, but not when we press MEDIA. We're even able to press the command button on the steering wheel when in the PHONE menu and tell the car to play Bluetooth audio. This however only worked once and since nothing in the sync system is working: the media button, the phone button, the voice command, the media and/phone menu section. The USB port and Aux port also no longer work, I believe that is related to the media not working. I did recently upgrade from an iPhone 7 to an iPhone 8 Plus, so I was thinking it could be compatibility issues between the new phone and the SYNC system, but my boyfriend?s iPhone 6 won't connect either - it always was able to before. Anyone have any ideas? I really don't want to take it to the dealer if there is a simple fix but we're out of ideas. Thanks for any help!

When I select Sync voice and ask for services 40% of the time it will not connect. It just goes back to the song on the media player I am using at that time. I live in a area where there is no trees so reception should not be a problem. I tried repairing my phone, master reset, factory defaults and disconnecting the battery for 30 minutes to allow Sync time to reboot after reconnecting the battery. Nothing works, does my Sync need replacing or what?
