Hello Enrico, yes, this is the expected behavior. The img file has to be created in one single part, otherwise routing over the boarders is not possible. At the moment I am looking for a solution for 2 very big parts, which are in total bigger than 4 GB. One idea is to splitt POIs, ways and areas into 3 layers and generate every layer into one file. I have not done it yes, but it could work.

Folks, if I download two countries pbf from geofabrik, merge them via osmosis and then build a single img map routing works fine across the countries. If I create two img files, one per country and put it on my garmin device, enable both maps, I can see all the ways seems correctly linked but routing across the two countries (maps) fails. Is that the expected behavior or am I doing somehting wrong?
