On their website it says “Map data can be captured on any SD card, including Garmin LakeVü™ HD Ultra maps, BlueChart® g2 charts or BlueChart® g2 Vision® charts.” Does the “any SD card” mean you can just buy a regular blank SD card or is it any SD card with some kind of maps on it. With Humminbird you need to purchase the Zero Lines card as far as I know so I’m trying to determine the differences.
