I am using various external controls (radios, auto-pilot, switches, Peix GlassCockpit on Android etc.) to interface with MSFS (mostly via FSUIPC & SimConnect, I believe). However, since SU5, things have gotten worse in terms of external controls and MSFS interaction.
Also, it seems that since SU5, the MSFS auto-pilot and avionics displays have gotten worse, in terms of showing the correct A/P modes on the Garmin panels etc.
Is there any remedy to this? What is my best bet to fly IFR in MSFS that provides the best compatibility as well with external controls as well as with internal displays? Any of the stock / free aircraft with any mods any good? Ex: If I press the HDG button, I want HDG to light up on the G1000. Same for climbs, ALT, ALT capture, NAV, APR capture etc. Is this at all available in 2021?
Your input is appreciated.
