Good software for mapping with Rino 530 GPS?

Not sure how easy it is, but it's certainly possible to use Google Earth with your GPS. I think pretty much any software that can deal with gpx files can if you look around a little. I do it by creating points in a folder in Google Earth and then save it out as either a kml or kmz. You can then load that file with this program (http://www.gpstm.com/) and upload to all kinds of different GPS. You can do the reverse and d/l from your GPS as well. If you want to get real technical with it, there are even ways to get that program to read your NMEA string and give you a real-time updated placemark in Google Earth...lol.

Yep, I use LoadMyTracks (For Mac, sorry) for moving waypoints/tracks/routes to/from the GPS. Editing and organization I just use a text editor for... GPX files are pretty easy XML. Use whitespace right and you get a pretty GPX file full of waypoints.

End of the ride I dump what's in my GPS into the folder I keep the pics from the day in. Google Earth will plot that data.
