"Round Trip" Option in Route

1 week old Prius v trim level 5

Tried to set a round trip option on a route prior to leaving home.I I followed the instructions in the 2011, Ver U 11.a01, "Display Audio System Owner's Manual" from the "Route setting" section, page 64.

The last image on the left hand side of the page shows two options which do not appear on our Prius v display: "Show Route Alternatives" and "Make a round trip".

So how do I set up a round trip?
