<div>Ok, I accept I just don't know how it's done. So how is
that done? How do I tell my Garmin to guide me along, say,
the Limes trail through the Netherlands? <br>

<p>Essentially, you'd just look at the screen and follow that! I
tend to use waypoints for an idea of things like "how long will it
be until I get to where I'm going to stop for lunch", not for
"turn left here because route XYZ turns left here", because you
can see on the screen that route XYZ "turns left here".<br>
</p>
<p>If you want to add a series of waypoints and route along those
then you can, but want you can't typically do with one of the
hiking-oriented Garmins is follow a particular feature. You could
create an OSM-based Garmin map that forced a device to route along
a trail at the expense of any other paths, but I certainly
wouldn't want to do that as it would stop me from leaving the
trail to eat in a nearby town.<br>
</p>
<p>Creating a Garmin route from a GPX file is possible, but probably
impractical, as you'd need to restrict the number of points.
Apparently my GPSMap 64 supports 200 routes with 250 points per
route, and up to 5000 waypoints in total.</p>
<p>Where Garmin on-device routing is really useful is for when you
need to get to somewhere but don't have an on-screen route to
follow - for example if the weather's turned and you need to abort
a previously planned route and get another route to your
destination from where you currently are. It's also useful where
there are natural obstacles like rivers, where the distance on
foot may be significantly more than the as-the-crow-flies
distance.<br>
