The coordinates in the Compass are different that in the Wayfinder.

Here is the question. I just found that the coordinates in Compass is different from that in the Wayfinder. I put the coordinates on the google map, and it seems that the coordinates in the Compass are exact my present location. Although the coordinates on the Wayfinder are near that in the Compass, there is a deviation. It seems the problem is trivial. However, if I need the rescue in emergency, I could get the wrong coordinates that nobody finds me. I think the coordinates in Compass shall be the that in the Wayfinder. 

Does anyone have the same problem?
