Marine Device Software Updates

Updating Handheld/Portable Devices

If your device has removable batteries, such as 2 AA batteries or a lithium-ion battery pack, then it is a handheld/portable device. You can update your device software for free using WebUpdater and a compatible cable.

Updating Fixed Mount Devices

If your device needs to be hard-wired to your boat’s power supply, then it is a fixed mount device. You can update the software by inserting a data card containing a software update bundle into your device.

You have 2 options for obtaining the update bundle:

1. Do it yourself: Download the free software update bundle to a data card (SD™ card and card reader or Garmin Data Card and Garmin Data Card reader required).
2. Purchase the software update bundle on a preloaded data card.

Use the table below to choose the appropriate software update bundle based on your installation and device’s card format.
