I have a Garmin GPmap62st.
When I download compiled routes from the web, I notice (1) the waypoints start with 01, 02 etc, and (2) they seem to be internal to the route, that is, they are not listed separately on my GPS, and when I am no longer navigating a particular route, they are no longer individually available on my device. This makes it possible to have many routes all numbered from 01 upwards.
In any route I compile, as well as forming part of a route, the waypoints are listed as individual waypoints. If I attempt to delete an existing set of waypoints to make way for a new set also beginning with 01, these waypoints disappear from the route they were part of.
How can I compile routes with characteristics (1) and (2) above on Basecamp?
