BMW X3 bluetooth problems with lumia 830

The phone pairs ok, you can even browse the agenda. You can dial but you wont even hear the dialing tone because it then switches back to the phone and leves the car BT system blocked. Something similar happens when you receive a call, you just press the answer button on the dashboard and it ends the BT
connection going to local. There is never audio throught the BT connection.

The Car is a 2006 BMW X3 with a standar BMW hands free kit (ULF). I had no problem at all with my previous phones. Is there anything I can do?. This is really frustrating !!!.

Try turning off your wireless and see if that helps. I have numerous Bluetooth problems with wireless turned on, slow connection with my car, my band and Bluetooth speaker.

Also, try the "advanced" Bluetooth option.
