Without riding it first, I mean.
I have a Garmin eTrex Vista Cx, (just replaced by Garmin on a £57 refurbishment deal, because of turning-itself-off-itis). I usually manage to download a track when riding Audaxes, as they seem to me to be the most reliable form of route following.
I know how to create a route. Is it possible to create a track?
