Here's a walkthrough on creating open source maps that should help. Bear in mind on the Dakota (and most similar Garmin products) that a file name can be called anything, provided it has an .img extension (and is under 8 characters IIRC), for example, rename the file NFRANCE.IMG. The CustomMaps folder refers to Garmin's own products and not user generated maps so don't drop files into that folder. It needs to live in the microsd/Garmin folder or the internal memory/Garmin folder. You can enable/disable which maps display so I would switch off foreign maps/other parts of the country when I am on my home patch.

There is another way of creating multiple map layers using Basecamp and writing one gmapsupp.img file but I don't tend to use that method as any update or change to one mapping product means rewriting the whole file.
