[mkgmap-dev] Maps with contours shows two maps in some devices (i.e. Zumo XT)

Hi Gerd,
Faced a similar problem today.
Perhaps this is a strange question, but I still ask it.
Is it possible to use MkGmap to convert multiply input files to _single_ output IMG map file ?
NOT a container like gmapsup.img
For example, I want to convert: 1 .osm and 1 .mp [with same BBox] => single .img ?

>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.

>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?
