Is the order of the command important? I'm trying to think through your first step. Sorry, can you clarify that better? I don't have one of those dongles that allow you to plug in an SD card and then connect to the garmin. I do have and external hard drive that I could directly connect to it, but I'm not sure how I'd run commands from the garmin using the newly created garmin folder. I do have the ability to plug an SD card into my computer though.
