There is lots of discussion about this in the official thread for this optional mod to the G1000:
https://forums.flightsimulator.com/t/working-title-g1000-nxi-discussion-thread/435492
I would suggest having a look there and maybe asking the question in that thread after seeing if your question is answered.
It is my understanding that eventually this will replace the default G1000 in the sim in a future game update.
Closing this for now as referred to the best thread for raising this question.
