Thread: Unlocked map not detected by 3790T, but works fine in 265

Thank you for your reply catymag.
I tried that already. I created a folder called Map on the SD card and placed the map img in the folder. I also tried creating a folder named "garmin" and put the img file in that. In both cases, the 3790t behaves as if it is not there. On the main memory of the unit, I transferred the img file as gmapsupp.img into the hidden folder ".system". Again the 3790t does not see the map.
