You have selected Microsoft Windows as your X-Plane platform, and the Garmin 400W/500W Series Trainer
software as your GPS
device. There are two ways you can put this together.
Use RealityXP's GNS 430 or GNS 530 programs.
These programs are built around the 32-bit Garmin GNS
430AWT and 530AWT Trainers, and are integrated with X-Plane,
requiring no additional translation software.
