Although this thread deals with zumo 550 and 600, the topic name is "zumo mapping naming", so I hope my following question is not considered off topic (I had a lengthy discussion with Neil recently about what is and what isn't off topic and my vision is blurred ever since... ).

The question being: do maps on a microSD for the zumo 590 follow the same naming convention as for instance for the nüvi 1xxx, 2xxx and 3xxx: anyname.img in the SD:\Map folder or does it go in the SD:\Garmin folder or does it follow the same convention as for zumo 550 and 600?
