That's great.

I have now determined the max number of nodes in a way that I can
have before a particular route on a particular map goes wrong on an
etrex vista. The max number is 18. So, while 30 may work in other
situations, it won't work for all maps/routes/gps's.

I don't believe there is a huge cost in space/speed if you break a way
into segments that have fewer routing nodes. After all, a large
proportion of the roads in the map will only have a few routing nodes
anyway, so partitioning a relatively small number of roads into segments
should have little impact on resource usage.

Cheers,

Mark
