Bluetooth Priority

Please, please, please Apple, give us Bluetooth Priority, I am tired of my Car-Bluetooth is taking over my calls when I am getting into the car.

Even more annoying is when you start a phone call in your headset (when sitting in the car) and the call signal is in your headset but as soon as the person you are calling answers it switches to the cars bluetooth.

Please give us the user the choice of decide which device is to be active.

The car-bluetooth is never as good as and B2B-headset.

So please....
