Bought a Phantom I from a private person. This Phantom was bought new from a dealer at the end of 2013. When I got it, I quickly realized that it wasn't able to find needed satelites..... Opend it, and discovered that the compass connector on the GPS unit was burned. The contact was infact just melted..... Sent inquiry to DJI support (Cause this is clearly a production fault), and was told to send the complete Phantom to my dealer, who then could send it to Germany for full inspection.I realized it would be much cheaper for me to just buy a replacement GPS/Compas unit and repair it my self... In addition to the money it would be just for shipping costs, I probably wouldn't have seen my Phantom again for several months........ NOT very impressive customer services by DJI.....
