Thanks for the reply ..... love some of the retrofits you have successfully implemented.I suspect the early posts all mention 791x because the digital dash was available across the pond before it was a available here. North America only got it in the 7.5 Golf R. By the time that was released people were already retrofitting the EU units.
After reading through multiple threads I came across many mentions of incompatibility between the different software revisions and installed Hardware. Very often these are not accompanied by the actual vehicle they were observed in. I don't know if these concerns were proven to be wrong.
