Hello !
i use the 737 fly engravity CDU with Project Magenta CDU and i notice some differences between the Harware screen and the PM on the monitor.
1- 1 cannot see the meessages in the fly engravity CDU
2-while in flights, the execute light won't light up
3-message light won't close
So up to now i cannot only use the Fly engravity CDU 1 always have to double check with the screen of PM
