WHY SOS FAILS

Hello, If you are pressing the SOS button, and no call is going through, you either do not have bluetooth or the telephone control unit is not functioning properly. Why would you have the button even though there is no way for it to work? Also the phone buttons on the steering wheel? These questions have been asked over and over, but, just a personal opinion, I'm convinced it looks better if every BMW has the cool buttons. If you do have bluetooth, and the SOS still will not connect, you likely have an issue with the telephone control unit, and you will need diagnostic software and a professional scanner to prove any kind of a diagnosis. If that does not answer the question, let me know.
