I live in Alberta Canada and I've had a number of issues since the July 29 update and the last one resulted in a significant drift and an unstable descent right into a swamp. I've actually had issues with my unit out of the box since day one.. I'm really not sure if it is related to the compass/declination issue though. The symptoms were intermittent. Please don't ask questions such as 'did you calibrate compass?' or 'did you do advanced calibration?', or 'did you have GPS lock?' or 'were you near electromagnetic interference?'. None of these were a factor as I had spent over 20 hours troubleshooting everything I could think of or read about on these forums. I'm aware of all of those items. Should I even bother purchasing another Phantom 2? I really want to believe that my unit was just a lemon since I see so many people claiming the latest update solved their TBE/hooking issue. Thoughts?
