Has anyone successfully paired theIr Skyradar L with the iFly app on a wifi only iPad 4? That is, are you getting both ADSB and GPS data from the Skyradar? Does the app support both the Skyradar L and an external GPS. I seem to be getting the ADSB, but get the message "no GPS lock". Wondering if I need to add the external GPS, e.g. The Dual XGPS 150A or 160.
