As I could not find any documentation about this function:
- What is the pupose of the buttons " - NTC 2.0 + "?
- I managed to manually add locations on the GPS screen, but whenever I choose one of the locations and go back, the line NTC gets not updated. I found out, that when I press the -/+ buttons it updates.

That number is the NTC (night time compenstaion) factor that is used in 'reference' value calculation.
In the case of 2.0 it means that if you set the 'reference' value during the day at night the 'reference' value will be 2.0 smaller then the one you set at day.
