I have searched and searched for a bluetooth solution for my 2004.5 S40. All of the youtube videos and forum tutorials that show how to install a bluetooth adapter show a plug on the back of the CD player. I took about the waterfall and pulled out the CD unit tonight, and my CD unit only has the optic connector on the back. There is not 14 pin plug.

Is there a simple bluetooth adapter solution for my specific setup? Any help would be greatly appreciated!!

This is the adapter I ordered from Amazon that did not fit.
