I am new to this Forum and Garmin Devices.
I have Nuvi 2547 LMT with Western Europe Maps. Firmware version is 7.80
I want to put Eastern Europe map on SD card. I tried using unlocked images but I get "cannot unlock maps" error. Does this means my firmware has to be patched? Can some one guide me on how to do it? I searched the forum for HWID number for this device but could not find in any list.
I appreciate your help.
