Different GPS units seem to handle this differently.

My eTrex Legend HCx shows the "description" field in the "Setup map" menu
where you can select individual map tiles. I set it like this in the
template.args file:

[...]
mapname: 10000058
description: OSM_Berlin_W
input-file: 10000058.osm.gz
mapname: 10000059
description: OSM_Berlin_O
input-file: 10000059.osm.gz
[...]

In the "Setup map" menu, where you can select the different maps according
to the family-ID and/or the basemap, it shows the family-name.

I haven't found the area name or the series name anywhere in this unit.

I copy the whole gmapsupp.img using an SD card reader.
