If you have a SD/MSD chip, please UNLOCK it first (locking mechanism pushed to the top of the card toward the contacts) and make sure your MSD card is inside of the SD adapter. The MSD card stands for microSD, and is the smaller card that can be found in the larger SD-size adapter. (You might notice that it has the amount of available GB on it.) This is the card that the data is actually stored on. The bigger SD card with the Navionics sticker on it is just an adapter to help you connect the smaller one to your computer.
