I appreciated your help Neil, but I still need the "Garmin Updater Files" which suppose to have these folders after you extract it, "3xxx series enable features application" folder, "For backup region 140.rar", "For write back reg 140.rar", and "READ ME.txt"...those files are mentioned on the instructions #4. Also, can I use a SD card that have other files in it that's not related to the Garmin files? Or does it have to be a EMPTY SD card?
