Check if plugin is installed correctly.
In the desired SD card create a directory Garmin and copy in it any file gmapsupp.img with some real .unl .
This is for bluecharts update, it needs an .img and an.unl

I haven't any .unl file on SD Card so maybe that is the reason why correct informations didn't appear in my case. I will try again with .unl file when I will be back home and I will let You know about results.

What map you try to unlock?

I am trying to unlock map "PL TOPO 2014.4" which I bought recently, however I think that if I paid for this, then I have right to use it also in my second device... Originally this map is locked and assigned to microSD card.

You cannot unlock "PL TOPO 2014.4" illegally, unlockers don't work with it, useless you try further, you can swap the sd to your 2 devices because the .unl is valid for the sd as you wrote.

Hi all,

I found your forum in my search for a way to unlock some Garmin maps I bought on an SD card. I haven't finished the process yet but I thought I'd add info about another way I found to get the serial number of an SD card, seeing as newer Garmins don't seem to allow this.

There's an Android app called "SD Insight" which will read this info from the card in your phone, you can get it from the Play store as usual. So, put the card in question into the phone, and run the app. It will show a screen with the card manufacturer's logo, the card size and manufacture date. Click the icon at the top that looks like an eye, this leads to a more detailed screen which shows lots of info about the card, one of the items is the serial number.

I hope this is useful to someone.
