I have updated the firmware of my 55LM to version 4.40 and the map South America 2016.10 is still working.
Some time ago I updated to version 4.30 and it didn't work, I had to downgrade to previous version; now with this new version it works, great news...
Because the map I'd downloaded said it was already unlocked, I simply copied onto the microSD card and got nowhere. But after reading your comment about using gimgunlock+magsigpatch, I tried that, and success!! Thanks very much for the advice - I'm so glad I came across this forum, not only for the help this time, but also because it's an entertaining read, and full of useful information.

Hello catymag, is there a way to know what software was used to unlock a map?
I ask because I downloaded a Europe map (CN Europe NT 2015.20 by mafozi) and it doesn't work with firmware 4.50 on a Nuvi 55
Can it be re-unlocked with the latest gimgunlock+mapsigpatch? or Do I need the original locked map?
Thanks...
You have to navigate to get to the good.
Galaxy S5 Kitkat 4.4.2 / Nuvi1200->1250 / Nuvi3790T->34xx / Nuvi 2200 / Nuvi 66 / Oregon 600
Wow! that was fast (you both were fast catymag) what a great utility this is, it fixed my Map in just a few seconds.
I've been trying to download a newer map but those zippyshare files are taking a lot to download.
I also distrust these kind of files, but I found this map before I found this great forum.
Thanks Neil and catymag.
