Did you verify this by the flight logs? I highly doubt that this was the issue, other than possibly with the Sat count on the display or lost in the translation and storage from the transmitted data stream which has nothing to do with the sat's locked by the AC. The aircraft .dat will confirm this if you are so inclined for curiosity sake.I removed it and tried the old apple cord and gps problem was gone. Don’t ask me why, I just telling you as it is
