Hi Marko,

Well, I chose 35000 because 39062 is too much of a magic number!

However, it would be good to find what the real problem is here. As I
reported before, I have a useful patch that removes nodes that aren't
really needed but I can't use the patch because although the maps are
fine for mapsource and the etrex, the nuvi barfs on them! It's bizarre.
I wonder if there is some stupid bug in the nuvi that we're hitting. I
have tried lots of different things (changing sizes of data tables,
etc.) but nothing seems related. Grrr.

Cheers,

Mark
