OSM map crashes in Garmin Nüvi 3490LMT

I have a problem with maps from South America, Chile/Argentina in particular. After using mkgmap, the resulting map crashes on my new Garmin Nüvi 3490LMT: the screen goes black and I have to restart the Nüvi. I thought, maybe it’s my map style? I tried Lambertus’s ready made maps, but the same happens. In Basecamp and Mapsource, the maps look fine, and on my good old Garmin iQue 3600 no problem either.

What’s happening here? Is there some OSM data issue the Nüvi can’t accept?
