Garmin GTN750 bezel provides an ultra realistic NAV/COM interface for your flight simulator. This is the best way to learn the functionality of the GTN750 and is much more realistic than using the mouse.
This product is especially helpful for learning and practicing instrument flying procedures. When coupled with virtual ATC like PilotEdge or VatSIM this provides the most realistic simulation possible. This allows you to develop familiarity with the Garmin GTN750 interface and controls so you can be better prepared for actual lessons with your CFII.
