Hi, can someone please explain to me how I can manually switch the connected phone to my wife's phone when we are both in the car? The system will connect to hers if she is the only one in the car and will connect to mine if I am the only person in the car. The problem is when we both enter the car, it will automatically connect to the last connected phone. If this happens to not be the current driver, there is no way to switch?? Thank you
