Hi Guys,
Not sure if this is the correct place for this question, but does anyone have any experience or opinions regarding the VR Insight CDU. As I am using the PMDG 737 with FS9, and the Engravity FMC is incompatible due to there being no interface, I seem to have no other option. If it is usable, can one update it with the airacs from Navigraph?
Another query, is the GoFlight MESM compatible with PMDG 737?

I would value your opinions, thanks,
