1. You will need a SD card at least 4GB. Format it using FAT32. Create a folder on it named "Garmin".
2. Place the gmapsupp.img (listed as IMG UNL above) and gmap3d.img (listed as 3D UNL above) in that folder.
3. In "Garmin" folder create 2 subfolders: name one "JCV" and the other "ASR".
4. Place *.JCV file (listed as JCV above) in the "JCV" folder and place *.ASR and *.SRX files (listed as ASR 3x90 above) in the "ASR" folder.
Folder structure should look like that:
/Garmin/gmap3d.img
/Garmin/gmapsupp.img
/Garmin/ASR/<filename>.ASR
/Garmin/ASR/<filename>.SRX
/Garmin/JCV/<filename>.JCV
I am working with a Nuvi 260 and a Nuvi 660. With previous map updates (maybe up to 2013.xx or so, can't be sure) I was able to simply put a gmapsupp.img file into the /Garmin/ folder on a 4 Gbyte SDHC card and the updated map file would be recognized. Lately, however, this technique does not work, the gmapsupp.img file is not recognized and the only usable maps were the ones in the internal memory.
I have since the tried the map files (.img, .JCV, .ASR), organized into folders and put on a 4 GByte SDHC card as described above (I could not find any .SRX file), but still no joy. Since one of the responders to this thread said it worked on his Nuvi 265, I'm assuming that it should also work on the Nuvi 260. The 4 GByte SDHC card is good, since photos placed on it are displayed on the screens.
Any clues what's going on here? I suspect cockpit error on my part, but at my age the mind is the 2nd thing to go, and I forget what the 1st thing is. Thanks for any help.
