Ok, I'm the last person that you should listen to, because I have no idea how to do this, however, the other day I was talking to the garmin guy and he sent me this link to Base Camp. Now I have no idea how to use it yet, and maybe never will, but this is the link he sent. I just started looking at it, and had to quit.
