[OSM-newbies] update gmapsupp.img

[Harald Kirsch]

Hi,

the OSM user ComputerTeddy generously provides a gmapsupp.img file that
covers Germany for use in Garmin devices. The file is produced with
mkgmap. Is there a way to update the file with new data in the area
where I do some mapping?

I am about to try mkgmap on gmapsupp.img and some fresh osm-data, but I
have no idea whether this will produce any sensible result.

Does anyone have more insight into this?

Thanks,
Harald.
