If you have the latest ANDROID version of FPG (I don't know what the IOS version looks like), there's a tab on the left labelled "External". You need to select "Dynon" and FPG needs to show "Connected". Once that happens, you should see a Up/Down arrow in the toolbar at the top of the Map screen. Tap that and select "Export to Skyview".
This used to be a lot easier when they only supported Skyview but it changed with all the devices they support now.
I really like FltPlan Go. It does everything I need, they have about the best Customer Support I've ever seen and it's FREE.
I am using the Android version.That's really weird. As soon as I do the export I get a message from Skyview telling me that it got a flight plan update.
As far as I know, if you get the Up/Down arrows you have a good connection. If you've done the export I don't think there's anything for you to mess up after that.
I'd contact FPG support about it (Support at FltPlan dot com). I've contacted them a number of times and they have always been super responsive. Just out of curiosity, are you using the Android or IOS version?
Let me check this before I send an e-Mail to FltPlanGo support. I am almost sure I have the SkyView as the map source but not sure of the HSI source.Make sure you have the Skyview map source and HSI source set as Skyview, not an external navigator.
