My iPhone 6 ringer volume keeps getting reset to maximum volume every time it connects to Sync 3. I keep turning it down, and it stays that way until I hop in the car. Next time the phone rings, it's on full blast again, even after I've gotten out of the car. Anyone else have this problem and know how to fix it? Not even sure if it's the phone or the vehicle that's doing this. Not using Apple car play, just regular ol' Bluetooth connection.
