Updating the Device Software Using a Memory Card

To update the software using a memory card, you must obtain a software-update memory card or load the latest software onto a memory card using the Garmin Express™ app (Loading the New Software on a Memory Card Using Garmin Express).

  1. Turn on the chartplotter.
  2. After the home screen appears, insert the memory card into the card slot.
    NOTE: In order for the software update instructions to appear, the device must be fully booted before the card is inserted.
  3. Select Install Now > Update Software > Yes.
  4. Wait several minutes while the software update process completes.
  5. When prompted, leave the memory card in place, and restart the chartplotter.
  6. Remove the memory card.
    NOTE: If the memory card is removed before the device restarts fully, the software update is not complete.
