Hi there.

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!
