You need to patch the firmware to use unlocked maps.

Read this thread software/universal-firmware-patcher-for-protected-garmin-devices-t17987.html

You will find Nuvi 57 patched firmware in the thread but you will have to search for it yourself

Depends on your device, but there is a KEY showing which JCV to use.

Hi
Which files are needed on the sd card of a nüvi 250W
Attached pictures are the existing info from the device. Western is on the sd card and central on the device


In the mean while I downloaded (9139) WesternEurope_NT_2023.10 and replace gmapsupp for the new one but it does not work so I think I have to do soemthing else to get it work.
Can someone help me out ?

First update your Firmware with Garmin Express to use a second map on an SD card
[Please Register or Login to download file]
On a Fat32 formatted SD card
Garmin/gmapsupp or Garmin/gmapsup1

There was a second map on the sd card as you can see on my previous picture.

This is my first time I use Express and the firmware looks up-to-date as you can see on the picture.
I only see the map which is on the device but the map on de sd card



Please advice me what to do

Update :
I just put the sd card in my PC but Express can´t find it

You don,t see the card in express but can you see it in your device. I suppose on the SD Card you have a folder Garmin and the map is in it.
I have a old nuvi 255 and don,t see the map on the SD Card in express but I can choise it in the Device (Nuvi 255).

@Holyhead that is correct, I can see it in the device and so I see one map is on the device and one is on the sd card and the map on the sd card is marked by a X so I think that one is active.

@GarmanNuvi I downloaded JaVaWa and will start it this afternoon
That went fast so this is the result of the manager, what should I do with it ?

Use JaVaWa to delete the OLD 2013 map from the SD card and replace with the latest 2023 with the file name gmapsupp.img .
I would also delete the gmapprom.img on the device as it is OLD as well and just taking up space.

Deleting done but which map should I download ?
Because I download (9139) WesternEurope_NT_2023.10 but that does not include gmapsupp.img but the gmapprom.img
There is 3,63GB free on the sd card and western europe was the map

Yes from new-maps/garmin-city-navigator-europe-2023-t22939.html#p187437
Just rename from gmapprom.img to gmapsupp.img
