Use with One Device Only

  • This download only may be used on 1 compatible device. Data downloaded to a microSD/SD card is associated with the device you select during the download process. Please purchase additional quantities for additional devices.
  • Reduced price map updates are not available for these cards. If you want to update the maps, you must purchase a new card that includes the latest map data.
  • For fixed-mount Garmin marine devices, you will be required to enter the serial number or unit ID for your device. Downloaded charts only can be used on the device with this serial number or unit ID. If you own a compatible Garmin Marine Network multi-function display (MFD), the chart card must reside in the device for which the serial number was provided. This device will provide the charts to other devices on the marine network, but the card will not be recognized if inserted into any other device. To ensure that marine BlueChart g2 and g2 Vision cards are usable without restrictions, Garmin recommends ordering pre-programmed cards or going to a retailer.
