The updated BlueChart line includes just two products: g2 and g2 Vision. The user can select the best cartography for his or her device from these two tiers.
Always make sure that your unit has the latest firmware installed to be sure of compatibility with the latest Bluechart g2 and g2 Vision.
Visit the Garmin web site to find out how to update your unit.
Note: Micro SD cards are supplied with an adaptor so that they can be used in micro or full size SD slots.
