As far as I'm aware there is no opensource OSM->routable-garmin
software, but there are non-opensource options available including
cGPSmapper. The one routable-osm map that I tried on my Garmin unit
(Venture Cx) had major problems with complexity - it couldn't route
more than about 7km in London before it became unusably long (>10mins,
I didn't let it complete) to calculate the route.

Cheers,
