I'm wondering how they control that though? It looks like you can mirror any app but if you start driving it's blocked from the system. So, there must be something in the app or more likely the head unit that hold's the certified list or checks the app. Given what the VCDS gang get up to, who knows.
Either way, I'll be hoping lots of app creators will look to get their own apps certified especially internet radio, travel and so on.
