I did obtain some gmapsupp.img containing the topo lines.

I used the following Command file on Windows XP:

Srtm2Osm.exe -bounds1 -23.0 163.5 -19.5 168.5 -step 20 -cat 500 100

and obtained an marvelous .osm file for New Caledonia.

(You have to download the Srtm2Osm tool first)

I failed to assemble the topo .img and the regular OSM data .img in
order to optionally display or not the topo data on the GPS nüvi
device.

I have just merged the topo .osm file and the regular osm file using
JOSM, but in this case it is not possible to switch of an on the topo
data.
