Garmin has a suggested supplier of the Costa Rica map (listed on the Garmin website) that I have been using for a few years. But, I am not able to import the map as it is an .img file. Anyone have any suggestions?
The GMAPSUPP.IMG file for Costa Rica supplied by "Centro GPS y Rutas Satelitales SA", a Garmin recommended supplier.
From the filename that IMG is only intended to be used on your GPS and not BaseCamp/Mapsource etc. As pointed out by OSTROFF01 already BaseCamp won't recognize that IMG. Perhaps the supplier sells a BaseCamp/MapSource compatible version of the map.

FYI gmapsupp.img is the default filename used by Garmin for its supplemental maps. Creating a device IMG with MapSource/MapInstall will silently overwrite that file if it already exists. Also, when purchasing a map product download from Garmin you'll get the same filename.
Many newer Garmin products, such as your 3490, support multiple IMG files so you don't have to use the default name. On my devices, that support this, I always rename any gmapsupp.img to something else. In my case I use
gmapsupX.img
where X is just a digit (1..9).
This prevents accidental overwrites.
PS: I also backup IMG's to other media "just in case".
I want to thank everyone for all their help. I have talked to Garmin (Jesse) and he made everything clear to just as you all did. I have contacted the distributor and am waiting for a reply but I think I already have the answers.
