So calls are made through bluetooth with android auto. I turned off BT. Plugged in USB, plugged it into the radio and BT turned back on. I made a phone call, fuzzy while plugged in, fine when unplugged. Then I turned off BT while still on the phone through the radio (but still plugged in) and it dropped the call from the car.
Well yesterday a call plugged in using android auto got fuzzy, I unplugged it and got better right away
