I am unable to get out of the CHKLIST menu in G1000. Upon attempting to exit the CHKLIST menu by pressing RETURN (screenshot #1), I'm presented with a menu (screenshot #2) that does not respond to FMS inputs. After about 3 seconds the entire menu disappears and the only softkey option presented is CHKLIST. If I press and hold CLR, SYSTEM and SHW CHRT softkey options appear momentarily (screenshot #3) but disappear as soon as I release CLR leaving CHKLIST as the only softkey option...
Addt'l notes: Re-installing TBM 900 resolves the issue UNTIL I attempt to use G1000's checklists again. Once in CHKLIST menu, the exact same issue occurs. Clearly a BUG that needs to be addressed by developers ASAP.
UPDATE (4/26/21): found https://forums.x-pilot.com/forums/topic/14717-solved-mfd-showing-no-map/ In my case, the issue seems to have been caused by the AVIONICS switch being set to OFF on my Logitech Pro Flight Switch Panel.
