How to update map data on GPS device?
You can update online here: http://www8.garmin.com/unlock/update.jsp (you must enter the serial number). Or you can buy from amazon (search for Garmin map updates). It comes in DVD-ROM which you download through your computer to the GPS via a USB cable (should be provided with the GPS).
But since you just bought the GPS, I think it should have come with 2008 maps, and there should be no need to update. Depending on the area where you live or travel, roads usually don't change quickly enough to justify updating more often than once every two years or longer.
