No d_s, the "nowarning" parameter always works for me on my iGuidance 2.1NA and beyond.
...both work great!
C:\Program Files\iNav\iGuidance>"iGuidance 2.1NA.exe" nowarning
C:\Program Files\iNav\iGuidance>"iGuidance 2.1.3NA.exe" nowarning
What you were talking about was my NO GPS "fix". If you don't have a GPS and you get the second NO GPS popup, just set your GPS comport to any one that is not in use. It is not really a NO GPS popup, it is more like a cannot open comport popup. I can't believe people run GPS emulators or want SKINbedder to click the 2nd prompt for them when all you have to do is select a non-used comport.
