Bluetooth malfunction - HELP

Re: X5 2006. BT was working fine wt my HTC incredible 2. Phone book did not sync but that was ok with me. Typically I turn off BT once in house and activate phone when in car without problem. One day got in car and phone would not connect. I tried everything. Resetting phone. Turning off and removing battery. I then noticed that BT appears to be disabled in the car. The tele button not fuctioning. Can't get to activate phone prompt. Checked fuses seemed to be ok. Eveything else is working radio all the panel lights, etc. is there a way to enable the BT or check anywhere else?
