You can specify a coordinate for this profile field. The latitudes and longtitudes values can be entered as decimal value with a dot as separator or - if you want to have no work - you can use the map that is displayed below this text. Best way is: Click on fullscreen mode, search the cordinate you need, click right into the map. The clicked point always gets centered after you clicked at it. The last click into the map is always stored and the coordinates are automatically filled into the coordinate fields below the map. This is done automatically and you will not see a bubble in the map or anything else. After clicking the coordinate minimize the fullscreen mode again. Then store your profile.
