Which one should I set them both to and will this stuff up my existing marks?

try adding a zero on the end..and see where/how that looks.

with my old yellow GPS when wanted to use google earth for marking clearings etc....I put the wee hand of google earth on my home,turned on ol yella...and kept changing format on gps untill both lots of numbers matched....

RUMPY has somehow managed to drag me into 21st century and got my newer gps set up correctly.


tell you what is a good ,fun and useful excercise when out on hill...pull out paper map,make best guess of your position,read co ordinates off map,write them down and then and only then ask phone/gps really good to see how close you are and great LEARNING exercise.

With LandSAR we have our gps' set on NZTM but we are also able to translate any format we are given, also as mentioned above aircraft mostly use lat/long.

From memory google earth uses hddd.ddddd your NZtopo 50 is probably set to NZTM (you can change this in the settings - under units)
