Hi folks im new here just found this great site the other day.  I have a question about the use of basecamp.  I currently have the etrex 20 and have my routes and waypoints backed up on basecamp.  My dad and i are heading to colorado in a month and he is considering getting a etrex 10.  Is it possible to add his gps to my basecamp and share my waypoints to his etrex.  Any help would be appreciated.
