No the GX50 will not fit in the Apollo Loran trays, But the GX55 will. I just swaped out my Flybuddy 800, It was a good unit but you can't get updates. To bad Garmin decided to screw the Flybuddy line and not support it. Lorans are a good navigation tool (cheap) if you can get the updates. If I had the panel space I would have keeped mine as a backup. I'm going to keep my and but it back in the plane and keep the GX55 if I ever sale my plane.
