Some software products and updates to them must be "unlocked" by you to access the data. Follow the instructions that accompany your disk to unlock it before downloading map detail to your device.
You must already own a map product to use an update. Update data will not load without an existing installation of the map product you own.
Due to the amount of content, some map updates are only available on DVD. You must have a DVD drive on your PC to install these updates.
Garmin strongly encourages you to take advantage of updated data not only to save yourself money, but to ensure that you have the most recent map data available. If you are entitled to a free update, we recommend you take advantage of this offer immediately. Free updates usually expire on the release of a new version.
