It is now available a wonderful freeware new version of the Cessna U206 Turbine mark 1 for P3D4 (and older) as well as for FSX  -  see announcement here:

It comes with a predefinition of the F1  GTN750 but I only have the RXP version for P3D4.

If anyone has replaced the F1 for the RXP GTN750 in P3D4 can he/she please post here the relevant parts of the panel.cfg of the Cessna U206?

Thanks
