I download nuvi34xx_GCDFile__710.gcd and use RGN_Tool. I click save boot.bin. I rename boot.bin to Ldr.bin. I replace it in X:\Garmin\Updater\1258\
Now I copy Garmin folder to root SD card. Insert to nuvi 3450 and it's not working. It go straight to where i need to click "Agree"
Got it.. I need to rename the folder 1258 to 1376
