How to adjust COMM1 volume using the GTN750?

  • This should be a simple question, but I can't figure it out. When I have the GTN750 option selected, how do I adjust the volume on COMM1?

    Initially it is zero, and the adjustment knob on the 750 frame is frozen in place.

    I can switch to the 530 and adjust it with the volume knob on that frame, but when I switch back to the 750 it goes to zero again.

    Hi Dutch,

    The top left knob on the GTN 750 should adjust the volume. The animation and volume work correctly here. Does it work OK on other aircraft for you?


  • Hi Martyn,

    Thanks for the quick response. The problem was a conflict with a lights mod in the folder 'justflight-aircraft-pa28-arrow-iii_PanelLightsWithNormalLanding' - removing that restores the knob functions. Probably that mod was for the pre-GTN750 version of the panel.

    Thanks for your support.
