Hello all, I recently traveled about 300 miles to fly phantom and when I tried to calibrate it the first step went fine but then when I turned it so the light was up and performed the second step in the calibration the red light flashes meaning that calibration failed. I was in large parking lot and had no metal objects on me (phone, keys, pants zipper, car). So I plugged it into my computer and all the settings I set were off (IOC FS) so when I went to check the box to turn on IOC it said "gps needed" and I am not sure how to get gps? Do I need to buy a part for it so it can get gps?
Thanks
Thanks
