I have an etrex Summit HC (i.e., with no external card, and (in practice 22Mb internal storage). I load relevant tiles from the set of .IMG tiles hosted by the SMC (http://www.smc.org.uk/ContourMaps.php). I use MapSource for selecting and loading relevant tiles.
There are several pre-built sets of tiles small enough for the 24 Mb limit, although the compressed MapSource distribution of Computerteddy seems to be stuck at April 2009. See the wiki page on http://wiki.openstreetmap.org/wiki/OSM_Map_On_Garmin/Download. for what is available. Tiles in the range of 1-3 Mb offer the best flexibility, larger tile sizes always seem to leave one on the edge of the map!
At any one time I usually have 4 SMC contour tiles, a reasonable area of OSM mapping around where I'm located, and several transparent overlays of OSM features which I am surveying (e.g., NaPTAN bus stops, noname streets) loaded on the Garmin.

Subject: [Talk-GB] Garmin maps no larger than 24MB
My father-in-law has a Garmin eTrex Legend C, and we'd like to put some
OSM maps on it for use when walking up hills in Scotland and the Lake
District. As he's a hillwalker, contours are important, but it only has
24MB of storage.
All the UK maps with contours are far too big to fit. Does anyone know
of anywhere that I can get maps of regions, that would be small enough
