I'm starting to think I wasted money on a product that doesn't work... I have the following code:

(* Take inputs for ECEF *)
x = Input["What is the x coordinate?"];
y = Input["What is the y coordinate?"];
z = Input["What is the z coordinate?"];

(* Put in Coordinate Form *)
GeoPositionXYZ[{x, y, z}, "ITRF00"];

(* Convert to LLA *)
GeoPosition[%];

(* Display Map *)
GeoGraphics[GeoRange -> "World", GeoProjection -> "Robinson"];

It converts the given coords in ECEF to Latitude, Longitude, Height... then it's supposed to plot latitude and longitude on a map. 1) It won't display any output at all because Mathematica is garbage. How do I make the software I paid six months of grocery budget for and am now eating ramen noodles and unable to pay my bills do what it's supposed to do and give some damned output? 2) Once it's giving output, how do I plot the latitude and longitude on the map?
