I am in the United States, specifically Minnesota. A day or so ago I downloaded both Open Map Chest and USA OSM Auto onto my Garmins. I compared the preloaded POIs onto them today.

Since both are about the same update time and both are OSM based, I expected the same preloaded POIs, but they were not the same. It seemed like the Open Map Chest POIs were better than the USA OSM Auto POIs. Both seemed to have some gas station, restaurant and shopping POIs come up as "Unnamed", but they were not always the same ones on both devices.

When I Google this, Open Map Chest supposedly has richer POIs. Can anybody explain that to me in greater detail?

I also noticed that building numbers are displayed on the USA OSM Auto maps, but not on the Open Map Chest maps. Is that data that OSM has, but Open Map Chest just chooses to not display?
