I’m not sure what Navigraph actually provides, but generally, the NAP’s are included in the Special Notices section of the chart supplements, not in the terminal procedure publication. This makes it more difficult to find the specific procedure for any given airport.
In general… NAP1 is used in the U.S. and NAP2 is used elsewhere. Lots of exceptions/differences, so that’s just a general statement that isn’t true for every airport.
