Hi guys.. new in the forum. I just recently purchased a 2007 BMW X5 4.8
Im kind of upset that the car does not come with a 6 cd changer so i purchased it. But first can someone help me with giving me some instructions how to take the head unit out so i can plug in the wire to the glove box? Any info would be gladly appriciated. Thank you guys and have a wonderful holiday..

By the way do i need to take it to a dealership to program the 6cd changer?
