The RealSimGear GNS430/530 is simply a control interface for your flight simulator. The knobs and buttons included on the RealSimGear unit are mapped to specific commands in your flight sim software. The display on the unit shows the GPS display from the simulation software.
A recent version of X-Plane also made it possible to 'pop out' the included Garmin 430 and 530 screen and position this on a secondary monitor. The virtual bezel for this display can be removed, enabling a near perfect representation of the actual Garmin 430 and 530 when paired with the RealSimGear hardware bezel.
The RealSimGear GNS430 and GNS530 consist of a custom designed printed circuit board (PCB) that has been fitted with switches for the various function buttons and two high quality dual encoders with their own push buttons for the radio frequency adjust and GPS page/chapter/cursor select. A 5" LCD screen connects to your PC via HDMI.
This is all packaged in a custom design bezel which replicates the real product. The bezel is molded in plastic and has been printed with labels. The product is fully enclosed and can be mounted on your desktop, or panel mounted.
