National Geographic has released TOPO! version 4.5, adding support for Garmin Oregon, Colorado, Edge and nuvi models. A Mac OS X version is also available. This is a welcome improvement, as too few mapping software programs support these models.
EDIT: The update allows transfer of data only, not maps. See the comments at the end of this post for more details.
While there are other great mapping programs out there, TOPO! remains my favorite for generating high-quality printed maps to go with me into the field. My normal practice is to transfer waypoints and tracks to TOPO!, and overlay it with a UTM grid for easily referencing my position.
Shown below is a map similar to one I created for a recent trip on the Eastern Slickrock Trail in DuPont State Forest (photo at bottom).

Rich,
What does support for the Garmin models mean? The ability to one click upload/download tracks/waypoints/routes instead of transferring gpx files? Or are they talking about map support? I'm assuming the former.
BTW, ExpertGPS also supports the Colorado and Oregon (send to/receive from GPS).

Ah yes, I guess I could have been clearer about that. I've sent my Oregon test unit back to Garmin and haven't tried this, but it should mean that you can transfer waypoints, tracks and routes from the Garmin device to TOPO!, and export waypoints and routes back to the device (I understand that better track support is forthcoming). And no, you can't transfer maps to the unit. Thanks for letting me know about ExpertGPS BTW.
