Afternoon Dirkclod, within the vision app you can see 3 - 5 satellites on the top right, but it is shaded grey. The yellow light is flashing top central saying no GPS lock. So, the app is picking up the satellites but for some reason it is greyed out, not normal, and the phantom isnt connecting? I did have a had bounce with it a few months ago, but have flown it since with GPS lock. Dont understand it why it has started happening? Any clues? or like you say, may have pulled the GPS plug may have come loose. The satellties are also intermittent, like, they have gone now.......0 sats now.
