After installing WebUpdater once from the Garmin website, perform all future software updates from your computer. Simply connect your compatible Garmin device to your computer, then run WebUpdater from your computer's "Start Menu" by selecting "Start", "Programs", "Garmin", and finally "WebUpdater"

Unless you bought the Lifetime maps you may have to pay for current maps.

A file is probably missing or corrupt in your Nuvi. You can call Garmin at 1-800-800-1020 and their software techs can remotely connect to your computer to check the files on your GPS to see if they are ok or not. There is a method where they create a file with your 25 digit unlock code in a certain directory to unlock the maps, but that information can only be received from Garmin.
