You said "would like to update (gmapsupp.img) map (with JCV. file) on a 8 Gb SD card" so we understood this old device had run out of internal space years ago.

Your device uses these NT maps which are the latest. Full Europe is 2 .img files now due to the 4Gb file limit.

SD card\Garmin\gmapsupp.img
SD card\Garmin\gmapsup1.img

Unfortunately, I don't know how to put spoiler here, otherweise I would do my Device infos and what I have done till now.
I have unpacked the 6 .rar files from post 3 and now have .gmap file with contents like post 4. Now how can I create .img ? and will it make automatically 2 different .img files (gmapsupp.img and gmapsup1.img) as you explained ? I am using pc
I have read a lot of post here and Tutorials, but now I'm very confused....

Forget about the gmap option these are the files for PC programs to create custom map sets.
The easiest is to use the 2 unlocked .img files shared directly from another members device.
All you have to do is download the 2 files from Post # 1 and arrange them on your SD card & rename gmapprom.img to gmapsupp.img as the above answer

I asked you to share your garmindevice.xml privately via my Drop folder so I could see what features your device uses.

Hello All:
I have been following this post for a few months. I have not seen ASR files anywhere. Does anyone by chance have the ASR1 files for this mapset ?
Thanks
