Our son just bought an '08 X3 in very nice condition. It was advertised as being "BlueTooth compatible". But when trying to activate registration with his iPhone 5, he discovered that the car has no TCU!
Did X3's come standard with a TCU? Or would have a TCU been installed only if the car was ordered with a special options package? How does "BMW Assist" fit into this issue?
Was the so-called BlueTooth compatibility claim just a play on words?
(Sorry for all these questions...we're still learning about such things.)
