The Oregon 700 is a very powerful and versatile unit. It does take time to get used to it so stick with it.
The basic functions that I use it for are
* Downloading tracks from my laptop, either from my own mapping software or from online sites.
* Recording a walk and then uploading to my laptop.
* Using the trip computer during a walk. I have it set up to display location, distance to destination, ETA at
destination, moving average and overall average.
The main screen i have set to show the trip odometer at the top with the where to, map, track manager, compass and trip computer icons. These cover all I need.
I am happy to help if i can.
