I looked at both the links. It appears they're using a more updated MMI (multi media interface) box. I can't attest to how CarPlay or Android Auto would work using these boxes. But if you want to see what is involved in installing a system such as this, look at the thread I created on installing the Bimmertech backup camera retrofit.
