My new to me 2010 XF 5.0 is giving me a fit with the Blue Tooth phone connection. Every now and then my phone will not connect to the car and when it is connected I can make and receive calls. Is this a common occurrence?

 

Every once in a while I lose bluetooth connection, then music plays through like a voice call and not fully through all of the speakers. I have to turn off the car and reconnect. It's not often but happens once in a while. Not sure why.
