Why not ask your question on the new OpenStreetMap Community Forum?

I am brand new at this, so please be as simple and detailed as you can. I purchased a Garmin Nuvi 42, and I would like to update the map of North America from time to time. Is there a way I can do this through your organization? Thank you.

Probably the easiest to follow set of instructions that I've seen are these. As far as I can tell from reading this, you'll need to get a microSD card if you don't already have one. As North America is quite large, I'd try to load a smaller map based around your local area first before retrying with a larger one.

There are actually lots of different styles of map created from OSM data for Garmin devices, but the site linked to from the above instructions is probably the easiest to use. It might also help to have a look at these previous questions - there may be answers there that are useful.
