+--- Thread: CDI button changes nav source on 750 and 650 (/thread-1854.html)
CDI button changes nav source on 750 and 650 - larrabeejesse - 10-07-2026
No matter how I configure the settings in the app for each unit, whenever I press the CDI button on either the 750 or 650 it changes from GPS to VLOC on both units.
When running the units outside of the MSFS2024 they operate correctly just like they do in the Garmin Trainer App.
Does anyone know of a fix for this behavior?

Hello,
This question has been recently discussed in our Discord, we invite you there for further discussions, here is our answer:
At this moment both GTNXi units are linked as internally MSFS still does not provide for two independent HSI units:

We are still discussing if we want to decouple them, as this will cause some confusion, since the second unit would not be tied to anything internally MSFS-wise.
If you desire independent CDI behavior, the TDS GTNXi XPlane offers this feature.

Thanks so much for the quick reply! I should have tried XPlane.
