JB4 Removal
 

I recently purchased a BMW 2 Series that had the JB4 tuner installed. Not wanting this performance module, I had an authorized dealer remove it. I would like to offer it to a friend who is interested in putting it in his vehicle. I took a photo of the removed unit(photo too large to attach) , that has the bluetooth attachment, but I am not sure if all the components are there. It has the main rectangular box with many clip-on connections plus the wireless component. According to the photo of a new unit, there may be another piece to the puzzle. Can you help?
Thanks
