[mkgmap-dev] Sub Descriptions in gmapsupps

From nwillink osm at pinns.co.uk on Thu Jul 3 16:02:31 BST 2014


On my Oregon 600 Garmin maps show a title and a subtitle in the 'configure
maps' setup


Digital Globe (title)
Demo JNX (subtitle)

So far I've not been able to create 'sub descriptions' using any of the
available commands

However, interestingly , I recently discovered that using Mapinstall I can
create subtitles but its messy.

I've done some testing 

1) using the following command I have create a gmapsup and installed the
same map on Basecamp.


2) On the Oregon the gmapsup (mkgmap.img) only produces:

'map4' as a main title

3) installing the map (mapinstall.img) using mapinstall I get

map1 ( as title)
map2 ( as subtitle)

4) looking at both imgs I noticed some interesting points:

a) MPS block 0x46 seems to contain the subtitle (in both imgs)
b) the mapinstall img contains an extra 0x50 block prior to 0x46

I can't as yet  tell whether 

a) this block present in tdb files must also be included in a gmapsupp?
b) There is some additional flag that is set?
c) or both?

Have included small osm & gmapsup files in
