I'm on FSX and contemplating making the leap to P3D at some point. Unlike the majority and in the interest of maintaining reality as a high priority, I often prefer the older GNS 530/430 to the newer GTN 750/650 in several smaller GA class aircraft. When reviewing avionics options for the latest Carenado / Alabeo releases, I notice the options are: 

Flight 1 GTN 750 (or 650) Integration;

Reality XP 530 (or 430) Integration (FSX Only).

The Flight 1 GNS 530/430 for P3D or FSX doesn't seem to be an option for VC integration; is that accurate? I understand the older RXP won't work in P3D, but is default the only option for 530/430? 

At present, there is no GNS addon gauge available for P3DV4..

Both RXP and F1 are working on it.. just give it time.. 

Got it. Thanks Bert.
