Hi
After an otherwise successfil re-installation of both airplane and PMS50 GTN750 (MSFS 2020 with correct livery choice) the HSI doesn't get any inputs from NAV1.
NAV2 works perfectly with VOR or ILS set and and DME works perfectly with both NAV1 or NAV2. Cannot use the autopilot with HDG or APR set.
Hopefully somebody has an idea of how to resolve that very annoying problem ...
