I just got my Phantom 2 as a package from B&H with all of the FPV and Gimbal pre-installed. I finally got everything charged up and went to do my first flight only to find that I can't even get it started. When I turn on the Phantom it flashes through Red-Green-Yellow and then just ends on a slow flashing yellow. I have tried to calibrate the compass and the horizontal goes fine and turns to green but after I do the vertical turn it just goes back to the slow flashing yellow. I have connected it to the Phantom 2 Assistant and it doesn't seem like the GPS is connected. I took it apart and the cord looks fine and it was connected. I get the same yellow flashing lights regardless of if it is plugged in or not. Does this mean that the GPS is bad, even being brand new?
