I've got a new Raven X and I'm experiencing very low Bluetooth phone call volume. In order to hear anything while the car is in motion I need to have the phone volume in the car at 8 or 9. I've tried un-pairing and re-pairing my phone and have verified that my phone's volume is maxed out. In my old Model S, a setting of 5 or 6 was sufficiently loud. What gives? Any advice?
