On the map how can I hide all other activities and just leave the one I want? If I want to view the route of that one activity, I get other routes overlapping and it still looks like a 3-year old scribble drawing.

I think I figured it out... like everything else with garmin this process is counter intuitive.
under Library you should have something called Collections I named it test
hit the Plus sign
give it a Collection Name
select the Activity icon (figure stretching arms and legs)
click "Select All On Map" (make sure the very first box next to "Name column" has a check mark)
unclick the one thing/activity you truly want to see
click Next
click Save Collection
once it is created go back to Collection
Click on the eye ball of the collection you just created and cross off the eye-ball
navigate back to Library - click on Activities
search/click for the one single thing you were interested in seeing in the first place 
then you will be able to see what you originally wanted, but!!! at this point you can start to turn off the eye-balls under Library to your liking to isolate what you don't want to see and strip it down to the very basic. play with each one at the time.
hope this helps. It is truly PAINFUL!
once you are done you can delete the Collections' item you just created without fear of losing all your Library items.
