Garmin Nuvi 50

Hi, i have just acquired a Garmin Nuvi 50. Can someone please give me some pointers as to how i get the latest maps for this and how do I put them on?

Thanks in advance

Make a folder Garmin on an empty SD card
Download an unlocked map (NTU 2017.10) and place them in the Garmin folder.
new-maps-f88/
If it is necessary rename the map van gmapprom.img
to gmapsupp.img.
Now you can select the new map in the Nuvi 50.

Like to hear the result Good or Bad
