Hullo all..New guy here. I got a D5000 for Christmas, as apparently many others did. I'm still learning, and will undoubtedly have many more questions. However, I figured I'd start with this one. I've seen some stuff saying that the Garmin ETrex Legend GPS can be used with the D5000, but I can not find the definitive answer. Can this GPS be used with the D5000, and if so, what is needed to make it happen?
