My cell phone is synced just fine, music works great, and my iphone 6S+ shows connected in the bluetooth menu.

But when I make a call, I can't hear the other person's audio. They can hear me (presumably thru the xc60 mic) but I can't hear them. Again - my iphone says it's trying to use the XC60. But the audio doesn't work.

Do I need to get an upgrade from the dealer?

Thanks
