The longest local route to me that I have worked on is over 5,000 km
long. I am certain that would not fit on my GPS as a route using this
method.
To reduce the gpx file it would be better to use the nodes where the
route changes from one way to another or where the way ends/starts. This
would leave the GPS to figure out that the internal map has a way
between those points and can use it That should be less way points. But
even then on my 5,000 km route it would be far too big for my old GPS as
one route. That is ok .. I'd separate it into bits.

That is what I do, and what an growing number of hiking people do:
turn a route into a gpx, load the gpx into an app or device, which
then routes along the gpx using all the nodes as waypoints. It works,
and it recreates the exact route if the map is exctly the same as the
original. And if the gpx is linear and without ordering problems.
And its crazy. Because the route is there to begin with, ready in OSM.
I still don't know how else to feed a pre-existing route to a garmin.
If it doesn't take the route from the map, and it doesn't take a gpx,
how does the device know where to go?

It may be possible...
Each node alone the OSM route would be a waypoint for your Garmin
device
as a route. There will be lots of waypoints!
You would need a OSM map on the Garmin device.
That may work... I am not certain if voice prompts would work, but
the
gpx file will be large, there may be too many waypoints for you
device
to handle.
The device will still be routing .. but between the nodes of the way
there will be no difference between the OSM map and the route.
Because of the large number of waypoints I'd think most people
will not
do this. If you chose to do it Peter, good luck.
