I use negative IDs in my non OSM data files to ensure they don't overlap. It doesn't seem to cause any problems and has the advantage that if I get any logged messages with negative IDs I know they are not referring to OSM data.

Is it important for you that you have the contours in a different map set? If not, I would merge the osm data and the contour data first, use splitter on the merged data to have a single map containing osm data and contours. That's how I create my own maps. The only problem that you have to take care of is that the contour data must not contain ids which overlap the OSM ids. I just noticed that my file Hoehendaten_Freizeitkarte_EUROPE.osm.pbf contains node ids starting with 7.500.000.000, so I have to create or download a new file now.

I create my maps with contours using the following command java -jar ./mkgmap/mkgmap.jar --description="$family_name - OSM" --output-dir="$dest"/ \ --family-id=10030 --product-id=1 --family-name="$family_name - Map" --route --remove-short-arcs --bounds=bounds.zip \ --precomp-sea=sea.zip --location-autofill=is_in,nearest --draw-priority=20 --gmapsupp --index --housenumbers "$work"/"$suffix"*osm.pbf ./typ/gspeed.typ \ --family-id=10031 --product-id=1 --family-name="$family_name - Contours" --draw-priority=10000 --transparent $contours ./typ/gspeedContours.typ In blue the part that refers to contours. Mapids for the two sets are different. On my Garmin Montana I see just one map with the name passed in --description option ($family_name - OSM). On an old Garmin Nuvi I see two maps, the real map with streets (named $family_name - Map) and the one with contours (named $family_name - Contours), which I can enable/disable individually. On the new Garmin Zumo XT I see two maps, both named $family_name - OSM. I can't disable just one of the two, they seems to be linked and it is weirs they show up with very same name in the list. Question: is there a way I can merge the two maps so I get the same behaviour anywhere? Thanks!
