XC60 Bluetooth audio issues
 

I have a 2012 XC60. I would say that the Bluetooth audio quality is not good. I have a hard time hearing the other party and have to pick up my handset (iphone 4s) and turn off hands free. Also, Siri basically doesn't work when it is paired to the car - no matter how slow and eloquently I speak Siri gets it wrong. This does not happen most of the time when using the handset outside of the car. Is anyone else experiencing this? Perhaps my system is bad and I need to get it replaced under warranty?

If not, and this is a good as it gets, then I am contemplating getting an external Bluetooth unit from Jabra or Motorolla to take care of this.
