First of all, I'm fascinated by this project and your building/coding skills. That's kinda sci-fi for me because completely beyond my personal expertise. My compliments to all of you and, specifically, to the man who invented it.
So, let's get right to the point: can anyone sell me the Bluesaab module and relevant harnesses?
Write to me. I have this "the most difficult part to get" which is cd changer connector harness.
Also, please contact this man: https://www.facebook.com/surforsink He is able to make a new one for you.
