If you need relief contours on your Garmin, you could try GroundTruth 
(http://wiki.openstreetmap.org/wiki/GroundTruth) - it generates contours 
from NASA's SRTM data (you'll get contours like these: 
http://www.openstreetmap.org/?lat=29.817&lon=85.091&zoom=10&layers=00B0FTF). 
There are some holes in the data though, so don't rely too much on them.

You can then combine these contour maps with other Garmin maps (contour 
maps are transparent).
