Does everything work? Audio menu in mfd? Convinience menu aswell? What gateway version do you have and what else have you changed?
Everything works, you lose the convenience menu, unless you upgrade your BCM. There is nothing important in the convenience menu anyway, all those features can be enabled/disabled by VCDS.
Gateway was upgraded to a 7N0 version. Everything else works properly.
We have sold plenty of these across the world since posting last year.
Any questions, happy to assist.
