Will anyone be kind enough to help and guide me so that I can once and for all learn and solve my questions.
It really doesn't help to link to other pages with miles of info that in the end it doesn't work even if a wrote many times which unit av Garmin I have.

That's try one more time...:-)

I have a nüvi 50LM.
I have a SD card named Garmin
In SD card I have a folder called also Garmin with one folder (JCV) and two files (GarminDevice.xlm and gmapsupp.img)
Folder JCV has one file called D3589040A.JCV

Is my folder structure right on my SD card or do I have to change something.

Which .img file works with my nüvi 50LM and please can you link to that page.
Which .JCV file works with my nüvi 50LM and please can you link to that page.
