I'm not interested in video playback. I'm not sure who thought that was a good idea for infotainment, given it's a huge distraction for drivers.
After extensive searches and reading, my conclusion is that it just isn't possible to swap out the factory MDI port with the one used in the MDI2 systems on newer models.
I don't know whose genius idea it was to assume everybody has an iPhone and essentially crippled those of us with Android since early MK7s don't support Android Auto or anything related to it, but that port is rendered useless for me. I'd like to be able to playback my hi-res audio with album art and that is not possible with the stock system. It says it will over BT, but it doesn't.
