Garmin

Update your Garmin chartplotter, fish finder, VHF radio, or GPS device with the latest charts and software.

Tip: Garmin Express is the easiest way to keep your device updated. Download it to your computer, connect your device via USB, and follow the prompts.

Simrad

Keep your Simrad NSX, NSS, or GO series chartplotter current with the latest firmware and chart updates.

Tip: Simrad updates are typically downloaded to a microSD card and installed directly on the unit. Check your model's manual for the correct procedure.

Lowrance

Update your Lowrance HDS, HOOK Reveal, or Elite series fish finder and chartplotter.

Tip: Lowrance updates are loaded via microSD card. Always back up your waypoints and routes before updating.

Raymarine

Update your Raymarine Axiom, Element, or Dragonfly chartplotter and sonar system.

Tip: Raymarine updates can be applied via USB drive or SD card depending on your model. Check the Raymarine support page for your specific device.

Alpine

Update your Alpine head unit, navigation system, or iLX series receiver with the latest firmware.

Tip: Alpine firmware updates are typically applied via USB drive. Download the update file, copy it to a USB drive, and follow the on-screen instructions on your head unit.

Tip: Kenwood firmware updates are applied via USB. Download the correct file for your exact model number before proceeding.

SiriusXM

Activate or manage your SiriusXM marine or vehicle subscription for weather, traffic, and entertainment.

Tip: SiriusXM does not require firmware updates — just an active subscription. If your weather or audio data has stopped, check your subscription status first.

Navionics

Update your Navionics chart card or Boating app with the latest marine charts and sonar data.

Tip: Navionics chart cards can be updated annually. The Navionics Boating app updates automatically when connected to Wi-Fi.

Best Practices

Update Tips

Back up your data first

Before any firmware update, save your waypoints, routes, and settings to a microSD card or USB drive. Updates rarely cause data loss, but it's always smart to have a backup.

Use the correct file for your model

Always verify your exact model number before downloading an update. Installing the wrong firmware can cause issues that require a factory reset or professional service.

Don't interrupt the update

Keep your device powered and connected throughout the update process. A power interruption mid-update can corrupt the firmware.
