Thank you @marx for your answer and for files you shared.
I think that gpsandmore_vr.zip is the same version I already had with 'stock' Gift. I already had autolocate entry in Voice recogniti9on menu.

Indeed some progress.
I have now VR microphone active.
iGO asks me in some foreign language to tell a word (I tried short phrases but they are not recognized)
and then a menu is showed with lines with result of search about the word I told.

Really basic functionality.
Of course some useful progress. I would like to translate to Spanish what iGO asks.
And be able to say basic commands.
How can I make additional progress?
