This started yesterday. I have the latest version of Sync and an iPhone 6s with the latest iOS on it. Neither have been updated in a few weeks. My phone will no longer connect to the car. I have done a master reset on Sync, reset all bluetooth settings on the car, did a network settings reset on my phone and rebooted the phone. I also tested my phone and it connects to other bluetooth items with no issues. I even deleted my phone from sync and sync from my phone. Now when I go to add a device my car doesn't give me a pin to enter when connecting a device. My car never finds my phone and my phone won't find my car.
Does anybody have any advice on something I have not tried so far? My next step is to reinstall the newest version of Sync to from a flash driver and see if that fixes it. Other than doing that my next guess would be to the dealership.
