iPhone 5S on iOS GM 10. Previous Bluetooth audio quality was fine. I am getting terrible quality audio when using Bluetooth in my car. This happens using Siri and while making a call. The audio is low and sounds almost "raspy" - like a cheap mono speaker over AM radio. I had to raise the volume from 20 to 27 just to be able to hear Siri and the phone calls. In an attempt to fix the issue, I deleted the car's audio system from the phone, and the phone from the car's audio system. I shut of Bluetooth on both devices, turned it back on, and repaired everything. No change. Anyone else having Bluetooth audio quality problems in the care, with a headset etc.? EDIT: Anyone have the link to report an issue like this to Apple?
