I'd ask this as a separate question, including a few more details of what you're trying to do and what Garmin you're using.

I've made changes on my city map with potlach2 then I've exported a selection. I've converted The file.osm to file.img and put it in map folder of gps Garmin Nuvi2797, it dont work. I've converted .osm to .gpx and copied it to GPX folder in Garmin, but nothing new in my osm map, no traces, no new waypoints :-( Thank you for helping.

I converted this from an "answer" to a different question. It's not clear if OP actually exported from P2 (where you'd get a .osc file I think?) or exported from osm.org (getting a .osm file) and tried loading that.

How did you convert the file? What exactly are you trying to achieve?

... and another question - what maps were on the Nuvi before? Garmin maps have family ID, and mkgmap uses a defalt for that, and if you already had another mkgmap-created Garmin map for the same family on there I suspect it might cause problems.

In order to avoid guesswork, it's great to add more detail. For example, we know you used mkgmap but what was the command line?

Potlatch 2 doesn't have any export facility at all so there's some confusion going on here!
