The unlocked image file for detail map can be put in Garmin folder named gmapsupp.img. Both 3D and detail images can be in a Map folder with '<any_name>'.img [both Garmin and Map must be in the microSD as root folders].

ASR/SRX files can go in ASR folder inside sd Garmin folder, but they probably won't be available for MENA. JCV file goes in JCV folder inside Garmin Folder. I think SID will also work that way for 3597. Or you can put them all in the appropriate folders on unit in .System folder. This is also probably moot for this map, but the SRD files will not work if placed in the sd ASR folder.
