Sorry to resurrect an old thread, but looking to do this to my '11 135i with HK/non-iDrive. Has anyone been successful with this head unit using the Axxesss harness? It's steep and I live in Canada, so I just want to make sure I've got the right one before I pull the trigger. The Connects2 one Stubbie suggested is like 350 pounds, so just trying to save a few bucks if possible
