[OSM-talk] Garmin Maps

[Ævar Arnfjörð Bjarmason]

Yes, such a project would be useful. I suggest you get in contact with
some of the people already running something similar, e.g.:

    http://garmin.na1400.info/routable.php

That project has selectable maps, a mapsource installer and more.
Presumably it could use some programming help to perhaps make custom
maps.

There's also style support in mkgmap, but I don't know of any nice UI
for setting those styles. Something neat for that would be nice, and
could be used by such a project.
