Though there is no particular requirement to do so, when maps are distributed as multiple “.img” files, use the mkgmap command “mkgmap –gmapsupp mapA.img mapB.img mapC.img ” to combine them into a single file.If the “Garmin” directory does not exist on the SD-card, one must be created. As with older devices, they must reside in a directory called “Garmin” on the SD-card (so the full path is “Garmin/*.img”). These devices can load multiple “*.img” files.img files you will need to merge them together – this can be done with the mkgmap command “mkgmap –gmapsupp mapA.img mapB.img mapC.img ”. There can only be one “gmapsupp.img” file, so if the map is distributed as several.If the “Garmin” directory does not exist on the SD-card, you will have to create it. This file must be in a directory called “Garmin” on the SD-card (so the full path is “Garmin/gmapsupp.img”). The Garmin device loads a single map file called “gmapsupp.img”.To use gmapsupp.img maps, simply copy the “gmapsupp.img” file to your Garmin. Select the Map you want to download and “right click” on it.
