The links in post #1 are great but a little confusing. Can someone please explain why there are 3 JCV files on offer? Which is the correct one if the 2012.20 is being installed as gmapprom on a 1490T? And a question I did ask several days ago but seems to have been ignored as the site went down for the last few day - Should there not also be a G2S file for 2012.20??? There is one on offer for NTU 2012.20 and for NTR 2012.20.
