I dont use Ozrunways but I assume you have the USB stick that has the Ozrunways installed in your Dynon USB port?
You can check if Dynon is seeing it by going to Setup menu then local display setup then installed databases. If the usb stick with the ozrunways is installed in the dynon usb port, you should see data from OZrunways in the installed databases listings. If you dont, then I would suspect that maybe the folder structure/files on the usb stick isnt exactly in the format that dynon is looking for, try different usb stick? At least that would give you a starting place to see if dynon is seeing the files.
