A couple of thoughts spring to mind now I've got the device up and running, sorry if someone else has already mentioned these, I couldn't see anything about the data side of things....
1. is poss to integrate a USB GPS dongle saving the wifi connection to the device? and if not..
2. could it connect to the device over Bluetooth instead ?
Reason for asking is my iPad has a data sim installed and as I fly along it updates SkyDemon's data, weather, metars etc,(handy on those long flights) but obviously once the iPad is connected to a wifi network all data from the sim stops as it assumes it has internet access from wifi.
I'm not clever enough to come up with the solutions... just asking the questions
