The Garmin "mapinstall" program should see your SD card and install your maps on the device and/or card. Make sure your SD card is good and formated.

Which model of Garmin? Some wont see maps on the SD card. Does yours have maps on their already that you are updating?
Look at GPS underground for all you'll need but I think registration is now needed.
