Hello, my device is montana 680.
I am trying to load this map.
new-maps/city-navigator-europe-ntu-2020-fid-8360-t21582.html?start=15I researched a lot here and applied what was written, but I was not successful.
Here's what I did:
1. SD card formatted FAT32
2. montana patch. I tried to apply what was written here. When I turned on the GPS, the load screen came up and the GPS was turned on. but I don't know if the patch was installed properly.
software/universal-firmware-patcher-for-protected-garmin-devices-t17987-405.html?hilit=montana#p1760963. I created two files inside the sd card. (Garmin and Map)
/Map/Gmapsupp.img
/Garmin/JCV/D6212110.jcv
Maps appear in the basecamp program, but the maps are not displayed on the device. I tried it on other maps, but the sd card does not see the contents. I throw a photo into it, the device can see it. my device only does not see map files.
I don't know where I am doing something wrong or incomplete. I need your help a lot. Sorry I'm a novice user.
