Thread: Garmin Thailand Street Map NT v10.0 EN+TH ( IMG Unlocked)

I have a nuvi 1340T which I purchased new in the U.K. it came with a pre-loaded European map (CN EUROPE NT 2010.10) I have been trying to load the Thailand Street Map NT v10.0 EN but without success. The Garmin folder of the unit contained just one file garmindevice.xml there were no .img files installed anywhere, I have unzipped the unlocked TSM v10 file and renamed it gmapsupp.img and moved it to the Garmin folder in the internal memory but it is not recognised.
What am I doing wrong?

Some newer Garmin devices 1xxx have hidden folder named "System", so You have to turn ON displaying hidden and system files in Folder options of Explorer to see and open it. In this folder you'll find .img file. Rename downloaded file exactly same as this .img file and put it in same place. Backup old file before, just in case...

Thanks for your quick reply.
You were spot on about the hidden system folder, it contains 3 .img files. (gmapbmap.img gmapprom.img and gmaptz.img) I have moved the TSM v10 into the folder as gmapsupp.img but it is still not recognized. Should I be replacing one of the files already there with the new one?

Navigation map is gmapprom.img, this one should be replaced, rename new map as this one gmapprom.img
other two files are:
gmapbmap.img - base bitmap (should remain)
gmaptz.img - timezone info (should remain)

I now have both the Thailand map and the European map loaded in the internal memory of my nuvi, I have renamed one as gmapprom.img and the other as gmapprom1.img the unit does not recognize gmapsupp.img files.
My first question is If I want to load any more maps can I simply rename them gmapprom2.img, gmapprom3.img etc, etc or is it more complicated? and secondly the maps are currently in Garmin\System folder of the internal memory if I want to put maps onto an SD card should I put them into a folder named Garmin or Garmin\System.
TIA.

It's all explained by catymag here:

On SD card maps are in Garmin folder and named gmapsupp.img for compatibility with other devices, hidden System folder is only on device
