If you have *.unl/*.gma files on the 50 from an earlier map version then back them up and delete them off the unit.

There is a *.gma in /.system
After backup, deleted. Startup message changed to cannot authenticate map, still not appearing in MyMap

I suspect the *.gma file is related to another map on your device, not the CNE NT 2015.20 map you're trying now. After all, there is a Lifetime Mapupdate subscription linked to your nüvi 50LM. If that is the European map, there's no need to get any unlocked UK map working on the device. Further, your nüvi 50LM would need the NTU version of the European map, not the NT version. JCV for instance would not work.

Basically, if the downloaded unlocked UK map works fine on the nüvi 765, it should be recognised on the nüvi 50LM too.

Sorry the LM is not for Europe...
The gma is for another map in unit which I renamed and replaced with the this map.
On SD, I inserted later both NT and NTU maps, but none appeared

Tried a OSM map on SD, works fine.

Cannot authenticate map message is for preloaded map lacking gma / unl.
Cannot unlock message is for your new map.
Check if it's really unlocked with Gmaptool/details log
It goes in sd/Map/anyname.img.

sent with my phone

....from the PC Installed version [gmap folder]. That way you can select only one or a few countries, or indeed just part of one country or even only one single map tile to send to your device.

is it possible to convert the gmapsupp.img to a pc install version (gmap folder) without losing the search function, or to make it mapinstall compatible. With GMapTool I can make it mapinstall compatible but like you say, the search function won't work.
How can I bring parts of a map to my gps from a gmapsupp.img (on a virtual disk) without losing any function?

Sorry no way, as written in a previous post, img contains MDR data (address index) but: (from Gmaptool Help)

Unfortunately GMapTool is unable to convert a MDR file from mapset into a format acceptable by Mapsource

Just one question, in the first post is not wrote if the map is unicode or not, but reading the other post seems that this upgrade is only unicode. I'm right...???
Now searching i got the unicode [Only registered and activated users can see links. Click Here To Register...], so this is NOT the unicode version.. Sorry to all...
