I recently fitted a RCD330 Plus Noname 6RD 035 187B from Lemon Shark into a 2017 T6
To make it all fit I had to additionally buy a "Quadlock Adaptor For VW/SKODA Radio Plug (2015-) To 2003-2015 Transporter T6 T5" -

It then powered up and the CarPlay worked fine (not tried Andoid Auto).
However the radio (FM & AM) didn't work because the cable that came with the RCD330 Plus from Lemon Shark was a single Fakra connector and my T6 needed a Double Fakra connector.
So I bought this:
Volkswagen Radio Antenna Adapter Double Fakra 20cm RNS RCD 510 310 315 to RCD330 / RCD360
With these two additional cables it was so easy to fit and works like a charm and you can have FM/AM radio in addition to using the Apps on the phone.
Hope that helps some people
