For optimal performance we have now included a switcher tool, located in the Start Menu (Just Flight > TB10 Tobago and TB20 Trinidad), which allows you to switch between two models:

Standard model - features the GNS 430. This is the default option.

Flight1 GTN 650/750 model - integrated Flight1 GTN 650 and 750, in addition to the GNS 430.

With the Flight1 GTN 650/750 model selected, you can switch between the three GPS options using the Add-ons > Just Flight TB10/TB20 menu within the simulator.
