@fildur
As I can see from your post, you have bought a "nuvi 3790T"
Your old Garmin Nuvi was with LMT (lifetime maps and traffic) .... So you need to find an post here with:
"City Navigator EU 2021.10 NT Unlocked" >
Or "City Navigator EU NT(Unicode) 2021.10 >
!!And Attention.... Read this linket Post Carefull

Make a back up of your garmindevice.xml from your nuvi 3790LMT & nuvi 3790T and keep them safe.
Copy your garmindevice.xml from your nuvi 3790LMT to your nuvi 3790T it will over write the original one.
Use Garmin Express to update your nuvi 3790T.
Use to unlock the .img files as they are locked to your nuvi 3790LMT."Cannot Unlock Maps"
You can buy a replacement screen, digitiser & bezel for with free shippingLast edited by Garmin_Nuvi; 20th December 2020 at 02:51 AM.

I also have a 3790T, but I have the problem that when I want to load routes with mapsource it happens that: -some are loaded well, -Others are not loaded (although they are in the GPX folder), -Others are loaded but with missing waypoints. I consult, is it a memory problem? why is this happening with the routes? Some routes are loaded directly into the device and they delete themselves.
I appreciate any information to solve this problem.
