Is anyone else having issues with low volume using a BT connection, such as Ford Sync? I deleted my old pairing in my vehicle, added the new phone, but every time I make a phone call, the volume is incredibly low, even with the phone BT volume at max. Is there any way to adjust this? I have to turn the vehicle in-call volume to nearly max to hear anyone. Comparing this to my previous M7, and other phones I've used, I would keep the BT volume on the phone at max, but the in-car volume at 50%.
