The Lat/Long given is in Guatemala. If you just cut/pasted it into Maps, it is not formatted correctly. Change the West to W and the North to N. i.e. 15 39 29.4 N, 88 59 31.8 W. You gotta know how to us Lat/Long!!
OK when posting this the "degree" mark is removed after the 15 and 88, also the "minute" ' is removed. The degree mark can be typed by holding ALT and typing 248. You will need those to get Maps to understand.
15 39' 29.4 N, 88 59' 31.8 W
