So far
1.) Open RGN_Tool --> drag nuvi34xx_GCDFile__820.gcd to RGN_Tool
2.) Save boot.bin and HWID # 1376
3.) Rename boot.bin to LDR.bin
4.) Extract Garmin+Updater+files 2
\Garmin Updater Files\3xxx series enable feature application folder
\Garmin Updater Files\For backup region 140\For backup region 140\Garmin\Updater\xxxx\update.txt
5.) Rename xxxx to
\Garmin Updater Files\For backup region 140\For backup region 140\Garmin\Updater\1376\update.txt
6. Copy LDR.bin to
\Garmin Updater Files\For backup region 140\For backup region 140\Garmin\Updater\1376\LDR.bin
the only other file in this directory is update.txt
7.)Format the sd card Fat32, then copy Garmin\Updater\1376\
to the sd card
8.) turn off 3490 , insert card, power up 3490, it's supposed to boot the card but it does not.

Thanks for the help
