Yep, I swapped from the smaller screen too and I'm really happy with it. I think more people go down the glass screen upgrade which is a really nice screen but I wanted to keep it inline with the mk7 options.
I got Alex at VW Retrofit to sort it, he managed to find me a used but excellent condition screen and swapped it all over for me. He did it really quickly and just had to adjust one of the plugs (as in shave a piece off) I think.
The surround was the most expensive part at £166

(I think I may have got 10% off this price from the dealer but still...)
