I've had problems the first day I get the car. Ok. I can't get my car to start. Since day one my aftermarket stereo had never worked. My cruise control, all the functions below the the air controls on my dash have never worked. Once I got a scanner that I made sure went with the BMW IT'S always read no communication. I'm troubleshooting more of it tomorrow but if anyone's ever had similar problems please let me know. Thank you
