Then find an SD card (the one out your digi camera will work - that's what I used) and run the software update on your PC, which puts the update file on the card.
Then take the card to the plotter, remove the map card, stick the update one in, power up. It auto detects the update file on the card, asks if you want to update or not, you say "yes" and 30s later (when it's finished) power down, pull the card back out & replace the map card. Job done!
....and you can tell it to Auto delete the update file when it's finished so you can put the card straight back into your camera!
