Just figured it out for you if you haven't already. Downloaded the file to the card (note: card was plugged into the computer directly instead of in the Garmin). After the Tour was downloaded, removed SD card from computer and plugged into my Nuvi 260 - the menu came up that new information was put on the disk, would I like to copy to memory in case disk was removed? I entered "No" and was able to access this Tour by pressing "Extras" and selecting what I wanted to view. Hope that helps. :)
Use SD Card w/o using memory of Garmin
