Possible to update the Nav data in Real sim gear GNS 430/530 and/or GTN 650?

Hi…,

The Realsimgear GNS530 uses standard X-Plane AIRAC data.

Please see FAQ - Installing Navdata AIRAC Updates

X-Plane 11 entry should be detected when you install latest FMS Data Manager. Select that in Addon List and download:

Please let us know how you get on.

Cheers
Ian
