Flight One Software has released the Flight1 GTN Complete Edition.

The package includes both the GTN 650 and 750 avionics (that used to be sold separately), in one package. This new version includes updates which allow the avionics package to work with FSX/ FSX: Steam Edition, Prepar3D v3 and the recently released Prepar3D v4.
The Flight1 GTN series 750 and 650 gauges feature fully integrated GPS, NAV, COM and MFD functions for all your general aviation aircraft. The large screen and intuitive graphical touchscreen interface give you quick and easy access to terrain mapping, graphical flight planning, charts and traffic display.
The GTN Avionics Series doesn’t use FSX/P3D internal processes to hinder simulation performance. All avionics data structures, calculations and processes are done separately to the sim, which allows the simulation to run much more smoothly.
The GTN Complete avionics suite includes a high-resolution moving map display with full data integration. The simulated touch-and-drag interface allows you to interact with the system, graphically edit flight plans and much more using your mouse cursor or a touch-screen monitor. Users will experience smooth frame rates while accessing SafeTaxi and FlightChart features that allow you to view detailed airport and terminal procedure charts within the user interface of the avionics. Full WAAS approach support, TCAS/TAWS system, airways display and many more features are included with this package.
Previous GTN 750 and 650 customers will have the option of upgrading to GTN Complete for free or with a small upgrade fee depending on what GTN 750 and 650 avionics packages they have previously purchased.
