Hi,

The only change I noticed when updating from 4.10 to 4.20 is the red colour of pathes and trails (when "activity" is on "hiking") that doesn't disappear anymore when changing zoom level on my Montana.
To see the named trails (if you have a Montana), select "trails" in "where to go" : as soon as you select "trails", click quickly on central button at the bottom of the screen, and named trails will be displayed.
But with this new 4.20 firmware, I still can't see the activity screen as shown in post 6.
