Anyone have a cd changer in the armest of your X5? I have one and a cd player in the deck. How do I get the changer to work?

cd changer on the armrest ? humm you most be talking about the cd holder on the armrest....

if you do have a changer on the armrest, maybe it was an after market unit installed by the previous owner..

Check BMW X3 accessory catalog, they have what you looking for.
It is factory BMW 6 cd changer mounted under the arm rest in X3 models.
