- Topo mapsets for Maine (50-ft. contours) and Massachusetts (40-ft. contours) available here.
- GPSFileDepot now has a topo mapset for Mississippi (in addition to its topo mapset for Arizona). New Mexico is coming soon …
- Ibycus has used 2007 Census TIGER data to generate a mapset (roads and geographic features) for the entire US. They also have a 1:50K-equivalent topo mapset that covers most of Canada.
- Routable street maps generated from OSM data for most of Western and Central Europe, Australia, New Zealand, the Philippines, and a few other scattered areas at the Open StreetMap for Garmin site. The map on the site’s front page only shows coverage areas; to get installable mapsets, or the original map code used to generate them, go to the Download Area. There’s also an additional mapset for Baghdad available on the site, but not yet listed on the download page.

Enjoy and have fun :-)
I downloaded and installed the mapset for Baghdad.
Sadly it ruined my MapSource. I had to uninstall the map to make MapSource work again.
Here’s a link to Switchbacks.com, AKA Northwest Trails, for the purposes of this post. Trails are catagorized into general groups. The compliation is great and is growing. In my area, anyway, the data has been of high quality.

From the swichbacks.com website:
What is Northwest Trails?
In short, Northwest Trails is a mapset of trails designed for upload to any map-enabled Garmin GPS receiver. It is more than just a mapset, though; it is also a community effort initiated to record and collect GPS data for trails in the Northwest (Washington, Idaho, Oregon, Montana, Wyoming, British Columbia and Alaska) and provide that data for general public use.
