I bought a 400t for geocaching as it was one of the only devices that allowed to download directly from geocaching.com.
When I tried to input coordinates under the form N XX° YY' ZZ.Z" and E XXX° YY' ZZ.Z" I could not find the functionality allowing me to do so. I could find all kind of preinstalled places, but it does not seem possible to use it a basic GPS and to input coordinates to get a azimuth and distance.
Can anyone help
