I know from someone who bought a new car from an European brand and the sales person couldn't get the the new owner's candybar phone paired with the car system for handsfree calls.
Instead of seeking some help from someone else, his suggestion to this new owner was "You should go and buy an iPhone or it won't work".
Obviously when I got to check it the phone paired exactly how it should and everything "Just worked" (TM).
*sigh*
