I've written a free installation program for Garmin's MapSource. It's aimed at the people who are maintaining Garmin map exports of the OpenStreetMap database. A lot of these exports[1] don't have a MapSource installer, some suggest proprietary solutions and some have a unconfigurable BAT file included or ask end-users to manually edit their registry after installation. I'd like to improve upon that, so I've written this: http://wiki.openstreetmap.org/wiki/Garmin_Mapsource_installer Here's blog post about it on the OpenStreetMap site: http://www.openstreetmap.org/user/%C3%86var%20Arnfj%C3%B6r%C3%B0%20Bjarmason... Like it says in the blog I'm interested in getting feedback / testing from users & map distributors on how it fits their needs. So please download the installer for Iceland (or make your own!): http://osm.nix.is/latest/default/OSM_IS_default.zip And tell me how installing it in MapSource goes. Whether you can install the map from there onto your Garmin device. And what could be improved about the whole process. 1. http://wiki.openstreetmap.org/wiki/OSM_Map_On_Garmin/Download
