TUNE NAV functionality not working

[362PC]

Looking for troubleshooting tips to get the TUNE NAV functionality working with the SkyView HDX and an Avidyne IFD 540. Not sure if this wasn't wired correctly by the installer, or if the configuration was not completed in both the HDX and the IFD. Recently watched this video on the Dynon channel and realized it is not functional on my setup.

Hints or pointers would be appreciated.

That video is on the COM radio, so it won't help you. In the info page on HDX, can you not select the desired nav signal source (ILS, VOR, etc.), and then see a "send to nav" button? I'm not speaking from experience, but from what I understand, "send to nav" doesn't appear until you select the source.
