Well, the guy in the "
Re: Sync 2 - Apple CarPlay/Android Auto Upgrade Kit" SZ thread says it works. I don't know which button activates it though, says long-press the "right-arrow" button or the "Sound" button???
From memory, my spare Sync2
ICC (that I never installed) does have all those plugs and having pulled the screen apart, also looks a lot like the bit you need to replace should all be good.
Maybe discuss it in that SZ thread, he may have more answers?
