http://www.openstreetmap.org/?lat=44.1481&lon=-71.6721&zoom=13&layers=B000FTF is an example of an area that is of interest to me. However, as I prefer simplicity of use over complete control, I prefer loading a 4GB SD card with the whole area I am possibly interested in (let's say, new england + NY + quebec), and then forget about it. 

Are you saying that it is an unreasonable use case ?

When you say "possible/impossible on MapSource", do you mean
"technically possible/impossible using Garmin's .img format" ?

What is the licensing problem that prevents creating routable + contour
maps ?

I'm sorry I'm not yet familiar with the GPS I just got, but please let
me rephrase that so I am sure to understand :

"it is impossible to create a contour + routable + hiking on garmin, but
you are circomventing this limitation by generating an additional
transparent background map that can be overlaid on top of any other map,
including hiking+routable". Is that what you mean ?

Also, I wonder : what is the difference between the "contour map" that
you talk about and garmin's official "topographic" maps ? Do the
topographic map contain more information than the contour ?

No doubt about that ;) The beauty of software development ;-)
