The format for Latitude and Longitude must be in EITHER degrees and minutes OR decimal degrees. The two formats cannot be mixed. For degrees and minutes, the data should look something like N18°12.345' or W65°12.345'. Note that if you cannot type the degrees (°) character, you may use the asterisk (*) character instead. For decimal degrees, the data should look something like 18.123456 or -65.123456. If you do not know the GPS coordinates, leave the default value (which is already in the correct format).
