I am currently looking to purchase my first GPS unit for outdoor purposes and am looking at the Garmin eTrex 20. However, I have a question relating to something I have not been able to find information about. \r\n\r\nFor instance, I pull off the side of the road in the general location of where I want to be. I mark this waypoint as my starting location. Can I then go into the GPS, add the lat/long of the place I want to walk to in the woods, and the GPS take me there? And then have the GPS take me back to my starting location where I started from.\r\n\r\nAny help anyone can provide is greatly appreciated. Thank you.
