Hi Les - To access the Route Timer feature click the TIMER option in the Action Bar in the bottom right corner of the map when editing a route or select it from the MENU on the route player when viewing a route. The speed/pace setting that you choose will then be used for the Virtual Partner when downloading a route. There is some more information about this new feature in our news post about the Route Timer.
I used to be able to set virtual partner speed when downloading to Garmin 1000. Now the instruction is to use "Timer feature" what/where is this feature??
