You can install the new GPS on most of your old aircraft. Just open Planemaker and load your aircraft. Under the standard tab, choose systems and (in the bottom left section) choose to use the new GPS for both pilot and copilot if your aircraft has both. Close that window and again under standard, choose 3D Panel and it will open a page onto which are placed all the devices used on the panel of that aircraft. Select the copilot's GPS device by left clicking on it. At the very bottom of that page is a bar with several things on it, but you only need to look at the last entry "copilot". Click in the box to select it, go to the top of the page and click on the save icon, hit the back arrow in the left of the extreme top of that page, go to file and click save. The new GPS is great, even though I haven't been through all of it yet, because you can click on the GPS on the panel of the aircraft you are flying and a 2D GPS screen will pop-up and you can change airport data, etc. with the roll of your mouse wheel or with clicks. When finished with your entries, click on the GPS on the 3D panel and the 2D will go away and the new information will be programmed in your panel. John
