I have a 2012 Honda and a 2007 acura. My phone works fine in the Acura but intermittently works in the Honda. It sees the phone, I make a call and then in the middle of the call, the phone disappears - the car shows not phone connected, the call is not disconnected so the person keeps talking, a few seconds later, the care finds the phone again and the call resumes. Its maddening. I have had the phone repleaced, I have the sameproblem. I upgraded the software. I have the same problem. I turned off Siri. I have the same problem.
THIS IS TOTALLY UNACCEPTABLE. I need to be able to drive my car and talk on the phone. APPLE SHOULD MAKE THIS A PRIORITY. THIS IS A SERIOUS DEFECT. THIS PHONE IS NOT FIT FOR USE AS A PHONE FOR ANYONE WHO NEEDS TO TALK ON THE PHONE AND DRIVE.
