If you design/plan the route on Connect or ridewithgps or whatever, you aren't using the 800 to design the route. You are just loading the route to the device. Loading routes has been a feature of the Garmins starting with the ancient 605.

Yes, you can plug in an address an such into the 800/810/touring units and have it compute a route for you (just like a car nvavigation unit).
The Touring computes three alternative routes or loop (round trip) routes and routes that minimize elevation. The 800/810 units don't.
