Forgive me if this has already been discussed, I searched but didn't see any definitive answers. Since the fuel computers have been able to be unlocked, I was wondering if the same could be done for CD changers. My single disc stock radio has the "load" buttons as well as "disc up" and "disc down", which makes me wonder if the unit the same as a 6 disc unit, with only the functionality disabled? I could be totally wrong, but figured I'd ask.
