Hi Troia
I'm not with Laminar Research, just a fellow simmer in the UK, but as I understand it, the C:\X-Plane 11\Custom Data\GNS430 folder only holds navdata for certain addon aircraft i.e.Flight Factor 757/767/777, JARDesign 320/330, JRollon Planes CRJ200 etc.
I also understand that all of the other default aircraft within X-Plane 11 get their navdata from the C:\X-Plane 11\Custom Data\CIFP folder.
So, no matter where you are getting your latest Airac cycle data from (e.g. Navigraph), you need to make sure that both navdata folders are updated.
Hope this helps :-)
Regards
