I think the point of Tilmann's notes in the FoxtrotGPS manual is that
`the vertices *are* the edges', e.g.:
* Do not set your waypoints on crossings. Instead, set them on the
road between crossings.
(and, now I notice that we should probably change those notes to ay
"routepoint" rather than "waypoint"...)
From what I've read about satnav units that support creating routepoints
offline, using just the software *on the device*, it seems like their
UIs typically do have that klunky worldview that the only routepoints
you'd be interested in setting are waypoints/POI where you'll want to
stop (and visit, and re-visit--some of them actually appear to require
that you save a waypoint into the POI database and then pull it up via
search before you can set a route through it...).
Even if you can't find an off-the-shelf satnav unit that does interactive
routeplanning straightforwardly like you want (like Tilmann's feature
in FoxtrotGPS does, I think), or a `handheld GNU/Linux super-satnav'
device, you might still be able to, say, use your N810 to program
routes into your Garmin when you're on the road..., maybe?
