I'll be interested to hear how well that works without using the Windows
GUI.

Ja, from what I've read, an SD card is usually what you store the OSM map
on.  It's unclear whether or not you can use more than one country map (or
in the USA, more than one state).  If it turns out to be a big hassle to
switch between the Washington state & Oregon OSM map on Garmin, then I'll
probably go back to using my very out of date (~2010) Garmin map.

Skal!
