Easy, when you have created a plan in Airnav and saved it, click on the GPS button (buttons on the second row), Airnav will ask if you want to save as a rte file (which is an Oziexplorer route file). Click save, then Airnav will ask if you want to save a wpt file (a Ozi waypoint file) click save. All you need to do is copy those two files from Airnav into the data folder of Ozi and go flying. Bring up the route in Ozi and the route and waypoints are all there. I use a card reader to transfer files, just copy and paste dead easy.
