TBM850 suffers from the same GTN750 CTD as Turbine Duke on Xbox

[stevemn]

Having purchased the Duke Turbine and had a problem, I foolishly decided to install the TBM850 and I now have exactly the same problem that I have with the Duke Turbine. With the GTN750 installed on either aircraft, FS2020 crashes every time. If I swap the 750 for other options, I have trouble free flying. Am I really the only one?
