Flying the G1000 SR22. When I switch COM1 frequency from what I set in standby, it just defaults back to something else. Can set COM2, NAV1, NAV2 no problem. Using PC with Logitech Radio Panel.
Basically on COM1 I am on 121.9 (a) / 120.1 (s) and when I go to swap them, it does it for one second then rewrites 120.1 to 121.9.
