First let me apologize, I have searched and searched and could not find my answer. So here goes. I have an 05 BMW 525i manufactured in 12/04. I am trying to get the cat and the phone to work. I go through the steps to hook it up and I get to a screen where I can choose either phone or Bluetooth but I can not check either one. Getting this fixed would make my wife very happy. And all you guys out there now "Happy wife Happy life" Thanks Ray
