Hi Rick,
The X-Plane GNSs load the X-Plane 11 navigation database, we don't have our own database loading, it all goes through X-Plane. Navigraph should install the X-Plane 11 data into the X-Plane 11/Custom Data folder. Note, this is a separate database from the X-Plane 10 "GNS 530/GNS 430" nav database, which isn't used by the X-Plane GNSs in X-Plane 11.
