Sorry for the late answer and thanks for the support!
I just made a test flight without the FSX-Borderless, and it look ok now, I'll make more tests.
Another thing I realized is that the Databases are soooo old! I bought the GNS530 just because is more common in aircrafts, and I can train with it for real life training.
Does the GTN 750 have a newer database or it's the same?
Is it possible to change?
