The car is not communicating (via BT) with your phone. Follow the procedures in the owner's manual for pairing your phone to the car. In a pinch, use the BMW Assist feature to get the m=number for BMW Customer Service and call them to walk you through the process.shawny said:In the communications section of the iDrive, I have a No Network message. All systems are turned off, and the BT does not work. Does any one know what the problem is?? How do I reset or fix the problem?
