VR Insight CDU/ Go Flight Multi Eng. Start Module

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,

Neil
