I am at my wits end trying to figure this out. I have a Skyview 7 inch display and all the Dynon extras (GPS,transponder,EMS). In addition, I also have an IFLY 700 GPS with external antenna and a connecting to Stratux ADSB-in. My issue is now I can operate both GPS units as both will not lock. If I turn off IFLY unit, Dynon works. Anyone with knowledge as to why this is happening? Previous flights both units work, not now.
