Dynon to Garmin Audio panel

[Setthrust]

Need help understanding where the mic/ptt ground ( pin#9) on Dynon x-25 goes.

i see no corresponding connections on the Garmin side.

Garmin's terminology for signal ground is "LO" so connect the Mic/PTT ground to COM 1 AUDIO LO or COM 2 AUDIO LO in your red-circled area.

Either can be used; they're connected internally and you can verify that with a continuity check using an ohmmeter.
