Hey, I have a Garmin Nuvi 50 and want to update the maps from 2012 to 2018. Here's what I've done to date:
For info, I've gone in to settings/maps/info on the device and there's only one map displayed. Any suggestions/help would be genuinely appreciated.

Thanks to all the responses in the thread, this was how I updated the UK maps on the Garmin Nuvi 50 satnav:
I've marked this as an answer - hope you don't mind!

What file system is the SD card formatted as? I believe they have to be FAT32 for a Garmin device to read them, but some large SD cards will come pre-formatted as exFAT.
Also, if you simply want to replace the 2012 maps with newer ones, all you need to do is put the gmapsupp.img in the same place as the existing one (the internal memory if you didn't have an SD card before) and overwrite it.
Thanks for the reply.
It's an 8GB, FAT32 format card. So, I could cut/paste the current gmapsupp.img (from the device) onto the sd card as a back up and then put the new map straight in to the device, right?
I just want to make sure I don't screw this up and render the unit completely useless :)
It may be useful if you would mention which site/URL you mean by "this site".There is not just one site which offers OSM-based Garmin maps. :-)Oh,sorry - I didn't realise: http://garmin.openstreetmap.nl
Yes, try it on the device itself. I did never hear that tinkering with the maps rendered a Garmin device useless.
By the way, at https://wiki.openstreetmap.org/wiki/Garmin/N%C3%BCvi_series#N.C3.BCvi_50 there is a small knowledgebase on your device. It really should work. The map names can be
whatever.img.Thank you.
I had a look at the article and it said "To override map in the built-in memory, replace .System/gmapprom.img"
So, I cut/paste that file on to the SD card as a back up and then copied the downloaded map (from http://garmin.openstreetmap.nl), named " gmapsupp.img" to the Garmin.System directory.
When I switch the Garmin device back on, it said something along the lines of no maps found. I checked settings/map/info (this was where the original map was displayed) and it was blank.
Hope I'm not missing something blatantly obvious! Thanks again for the help.
EDIT I just changed the name of the file from gmapsupp to gmapprom and that seems to have sorted it. I'll go out for a drive later and see how it works.
If this solution works for you then add it as an answer :)
I've tried clicking the convert comment to an answer but it's saying unknown error occured. I'll try again later.
In the meantime, thank you so much for all your help. I wouldn't have even got to load the map on to the device if it wasn't for the responses.
@IanPeter: that conversion does not work if there were edits to the comment. Just copy and paste the text. :-) Others with the same device will be grateful for an "answer".
