You wait for Garmin to release an update, and Garmin will not do that until the map makers have been to sufficient places to warrant the update, this means that it could be six months to several years before you get an update, and like some of my gps units, maybe never. Hope this helps. You could also try sending Garmin an e mail and beaking at them about the upgrade, might get you one faster, and also might not, but should at least get you an answer.
