Hi Terry,

I'm not familiar with the different coordinates conversion, but I routinely
use a GPS for flying (paragliding) and mine, and I guess almost all the GPS,
accepts all the coordinates systems, since the one officially used depends
on the country.

Have a look at your GPS menus and you'll probably find how to make it uses
the UTM coordinates.

In case you don't find it, make a file with all your coordinates, and I'll
submit it to the prog I use to manage my flights and I'll return you it
converted to the one you want.

Fred.
