Help! I cannot get iPhone 6plus to answer call via Bluetooth. I have paired unpaired and rest phone. Even turned on off the availability - call handling in phones settings. The phone will not connect the call 1st time, may do it second time. And so on... Sometimes a call will come through but mute the call volume. It is connected to the car but the call stays on he phone unless you push the button on phone to push it to car. What is good my on. Car is 09 st hdi.
