I can not get the correct GPS coordinates or the location is wrong

(1) Please make sure there is no metal obstacles above the tracker. Please place the side with GPS antenna upside to the sky;

(2) Please check it at broad place;

(3) Please check if the GPS LED flash once every 3 seconds; place the tracker to other place, so as to make sure that it can receive the GPS siganl well

(4) In cloudy condition, it is a little hard to get the GPS signal, and the GPS coordinate might have some errors.
