RealSimGear G500 + RXP GTN 650: CRS / OBS knob not changing

Hello everyone,

I am having an issue getting the CRS / OBS knob on the RealSimGear G500 to change the course on the HSI when paired with the Reality XP GTN 650 in X-Plane 11.

The Problem:

• The HDG, ALT, V/S, and BARO modes/knobs work perfectly on the G500.

• When I set the GTN 650 to OBS mode (green OBS active) and select GPS1 / CRS on the G500, turning the CRS knob on the G500 bezel does not rotate the magenta needle or update the course degree value.

• The course knob works for VOR/NAV, but not for GPS/OBS mode.

What I have already tried:

1. Set LinkHsi = true, LinkObs = true, and LinkVor = true in RealityXP.GTN.ini.

2. Verified that GTN 1 is set as MasterDevice and checked different AFMS.sel_crs_gps settings.

3. Verified Connect HSI/OBS settings in the RXP plugin menu.

Is there a specific Dataref mapping or a configuration setting needed between the RSG G500 plugin and Reality XP GTN 650 to allow the G500 CRS knob to drive the GTN OBS course?

Any help or suggestions would be greatly appreciated!

Thanks!
