I took the advice of those that review and bought two of these units. One formy wife and one for me. When it works it's great. Then it just doesn't. (Apple 6 by the way) It will start to call and you can hear siri and then you have to pick up your phone. It shows it's still paired with blue tooth but it just doesn't work. We are both at our wits ends. Is there a fix for this or did I just waste money because of our apple phones?
