yes, you can retrofit NBT, but it is not plug and play, you will need to code new unit, and activate FSC's.

yes you can upgrade to EVO but not by software, you will need to change hardware to EVO, but that is more difficult than regular NBT.

NBT GPS is easy, all you have to do is buy aftermarket GPS antenna which cost ~10€

Thank you.... I found one NBT retrofit kit on local ads for I think good price, would this work with LCI from 2015 ?

Regarding FSC coding and activation, can that be done by self via e-sys ?

Or maybe is best to let professional to that job, I saw some videos on YT, when guy fix everything via USB stick and scripts.
Do we have recommended FSC code seller here on forum ?
(EDIT: I saw you are FSC coder )
