Retail cards ensure that you stay equipped with the most current charts available. These easy-to-redeem cards allow you to download an update for existing Bluechart g2 Vision preprogrammed microSD/SD cards.
Redemption is simple; visit www.garmin.com/activatecard, enter the Product Key from the back of the card, then insert your existing preprogrammed g2 Visioncard into an SD card reader connected to your computer. The map data will then be replaced with the most up-to-date version available. Updated charts will be for the same (or equivalent) region as the existing preprogrammed card.
