Hi XXXXXXXX, in order to get your radio code you'll need to slide the radio forward and provide me with the radio serial # off of the plate on the radio. Then I can enter that # into the BMW database and retrieve your code. You should have 4 holes in the outer edge of your radio to insert the special tools to release the unit and slide it forward.
