Wanted to take pictures at an event this afternoon. could not get compass and GPS to sync at all. Only things I could think of is 1) I know there is a regional dispatch center 2 blocks away, 2) PD with tower on one side of field and 3) high voltage power lines running across the other side. I believe to much EMI. But when I got home, tried to get compass to calibrate and also had trouble..... any suggestions ??? Would like to go back to shoot events later today ??
