How To Fix a Smart Trolling Motor Firmware Without Wi-Fi?

You are out on the water, miles from the nearest Wi-Fi signal, and your smart trolling motor needs a firmware update. Maybe the GPS keeps glitching. Maybe Spot Lock drifts more than it should. The motor clearly needs new software, but there is no internet connection in sight.

This is a problem thousands of anglers face every season. Smart trolling motors from brands like Minn Kota, Garmin Force, and Lowrance Ghost all rely on firmware updates to fix bugs, add features, and improve performance.

But these updates often assume you have a steady Wi-Fi connection, which is rarely the case at a boat ramp or on open water.

In a Nutshell

• Bluetooth is the most common offline method for updating smart trolling motors. Apps like the Minn Kota One Boat Network app and the Garmin ActiveCaptain app can download firmware files using cellular data and then push the update to your motor through a Bluetooth connection.
• A mobile phone hotspot can replace traditional Wi-Fi during the update process. Your phone creates a local wireless network that your trolling motor or chartplotter can connect to for downloading the necessary firmware files.
• SD cards and microSD cards offer a fully offline approach. You download the firmware file to a computer at home, copy it to a memory card, and then load it into your fish finder or chartplotter to transfer the update to the motor.
• Connected chartplotters can push firmware updates to trolling motors through a wired or networked connection. Garmin Force motors, for example, can receive updates directly from a compatible Garmin chartplotter loaded with the latest software via an SD card.
• Pre downloading firmware before your trip is the smartest habit. Download the update file at home using Wi-Fi, save it to your phone or an SD card, and complete the transfer at the boat whenever you are ready.
• Always charge your devices and keep the motor powered on during the entire update. A failed update caused by a dead battery can sometimes brick the motor’s control head and require a factory reset.

Why Firmware Updates Matter for Your Trolling Motor

Firmware is the software embedded in your trolling motor’s control head. It controls everything from GPS accuracy to Spot Lock performance and responsive steering. Manufacturers release updates to fix known bugs, improve battery efficiency, and sometimes add entirely new features.

Skipping firmware updates can cause real problems on the water. Your motor might lose GPS lock more often, respond slowly to remote commands, or fail to communicate with your fish finder. Some updates also patch security issues in Bluetooth and Wi-Fi connections.

Running outdated firmware can also create compatibility issues with newer fish finders and chartplotters. If your Humminbird unit gets a software update but your Minn Kota motor does not, the two devices may stop communicating properly on the One Boat Network.

Common Smart Trolling Motor Brands That Need Updates

Three major brands dominate the smart trolling motor market, and each handles firmware updates a bit differently. Minn Kota motors with i Pilot and i Pilot Link use the One Boat Network app or the older i Pilot app. These apps connect through Bluetooth and need cellular data or Wi-Fi only for the initial download.

Garmin Force and Force Kraken motors use the ActiveCaptain app. They can also receive updates through a compatible Garmin chartplotter. This gives Garmin users two solid offline paths for firmware updates.

Lowrance Ghost and Ghost X motors take a different approach entirely. They receive firmware updates through a connected Lowrance display unit using a microSD card. This method does not require any wireless connection at all, making it the most straightforward offline option of the three.

Method 1: Use Bluetooth and Cellular Data

This is the easiest method for most anglers. You do not need a Wi-Fi router. You just need your smartphone with a working cellular data connection and the correct app installed.

For Minn Kota motors, download the One Boat Network app. Open the app, sign in, and pair your phone to the trolling motor through Bluetooth. The app will check for available updates using your phone’s cellular signal. Once the update downloads to your phone, it transfers to the motor through Bluetooth without any Wi-Fi involved.

For Garmin Force motors, the process is similar. Open the ActiveCaptain app, connect to the motor’s Wi-Fi network, and the app pulls the firmware file using your phone’s data connection. The actual transfer happens locally between your phone and the motor.

Pros: Simple, fast, and requires no extra hardware. Works anywhere you have cell signal.

Cons: Firmware files can be large. If your cell signal is weak, the download may fail or take a long time. Bluetooth transfers can also be slow, sometimes taking 20 to 30 minutes.

Method 2: Create a Mobile Hotspot

If your trolling motor or chartplotter needs a Wi-Fi connection to check for updates, your phone’s mobile hotspot feature solves the problem. This turns your phone into a small Wi-Fi router.

Go to your phone’s settings and enable the hotspot. Then connect your chartplotter or trolling motor to the hotspot network just like you would connect to any Wi-Fi network. The device will see your phone’s hotspot as a regular internet connection and download the update.

This method works especially well for Garmin Force motors paired with Garmin chartplotters. The chartplotter connects to your phone hotspot, downloads the firmware, and then pushes the update to the trolling motor through the NMEA 2000 network or direct connection.

Pros: Works anywhere you have cellular service. No extra equipment needed.

Cons: Uses mobile data, which could be costly on limited plans. Hotspot connections can be unstable in remote areas with weak cell towers.

Method 3: Use an SD Card for a Fully Offline Update

The SD card method is the most reliable offline option because it does not depend on any wireless signal at all. You prepare everything at home and finish the job at the boat.

For Lowrance Ghost motors, visit the Lowrance downloads page on your computer. Download the latest Ghost firmware file and copy it to a formatted microSD card. Insert the card into your Lowrance display at the boat. Then go to Pages, select Storage, choose the SD card, select the update file, and pick your Ghost trolling motor as the target device.

For Minn Kota motors with Humminbird units, you can download the update to an SD card from the Humminbird website. Insert the card into your Humminbird fish finder, and the device will detect the firmware. From there, you can push the update to the connected trolling motor.

Pros: No internet connection required at the boat. Very stable and unlikely to fail.

Cons: Requires a computer, an SD card reader, and a bit of prep time at home.

Method 4: Update Through a Connected Chartplotter

Many smart trolling motors connect to a chartplotter or fish finder on your boat. You can use this wired or networked connection to push firmware from the display unit to the motor.

Garmin Force motors support this method well. You can load the firmware onto your Garmin chartplotter using an SD card or by connecting the chartplotter to a hotspot. Once the chartplotter has the update, it sends the firmware directly to the trolling motor over the network. Garmin’s support page recommends placing the update card in the device that is not Wi-Fi connected for the best results.

Humminbird SOLIX, APEX, and XPLORE units can also pass firmware updates to Minn Kota motors connected through the One Boat Network. The fish finder acts as the middleman between your SD card and the trolling motor.

Pros: Uses your existing boat electronics. No phone or app required once the file is loaded.

Cons: Requires compatible equipment. Not all chartplotters can push updates to all trolling motors.

Step by Step: Updating Minn Kota Motors Without Wi-Fi

Here is a complete walkthrough for Minn Kota Advanced GPS trolling motors using the One Boat Network app and Bluetooth.

First, download the One Boat Network app from the Google Play Store or Apple App Store while you still have internet access. Create an account and sign in. Next, pair your phone to the motor by pressing and holding the Pair button on the trolling motor control head. Your phone should find “Minn Kota Controller 4.0” in the Bluetooth device list.

Open the app and tap “Network + Updates.” If an update is available, tap “Download Update.” The file downloads to your phone using cellular data. Once the download finishes, tap “Transfer Software.” The update moves from your phone to the motor via Bluetooth. The motor will power cycle once the update is complete.

Finally, update the wireless remote. Press the menu button on the remote, go to System, and select “Update Software.” The remote will pull the new firmware from the updated control head.

Step by Step: Updating Garmin Force Motors Without Wi-Fi

For Garmin Force and Force Kraken owners, the ActiveCaptain app is the primary update tool. Download the app and create an account at home.

At the boat, power on the trolling motor and open the ActiveCaptain app. Connect your phone to the trolling motor’s built in Wi-Fi network. The app will detect available updates. If your phone has cellular data, it will download the firmware file in the background.

Once the file is ready, the app pushes the update to the motor. This can take up to 30 minutes depending on file size. Do not power off the motor during this time.

Alternatively, download the firmware from Garmin’s website to an SD card. Insert the card into your Garmin chartplotter. Go to the software update menu and select the trolling motor. The chartplotter sends the firmware to the motor through the direct connection, bypassing Wi-Fi entirely.

Step by Step: Updating Lowrance Ghost Motors Without Wi-Fi

The Lowrance Ghost uses the simplest offline method of all three major brands. You need a computer, a microSD card, and a Lowrance display unit.

Visit the Lowrance website and go to the downloads section for your specific model. Download the latest firmware file for the Ghost or Ghost X. Copy the file to a formatted microSD card using your computer.

At the boat, insert the microSD card into the card slot on your Lowrance display. Press Pages, go to Storage, and select the SD card. Choose the update file and select “Upgrade.” Pick your Ghost trolling motor from the device list and tap “Start Upgrade.”

Wait for the display to show “Update Complete.” Watch the indicator arrow LED on the motor and do not power off until it stops flashing. This entire process works without any internet connection at all.

Tips to Avoid Failed Firmware Updates

A failed update can leave your trolling motor stuck in a non functional state. Follow these tips to prevent problems.

Always make sure your trolling motor battery is fully charged before starting an update. A low battery that dies mid update can corrupt the firmware. Keep your phone charged above 50% as well, especially for Bluetooth transfers that take 20 to 30 minutes.

Do not close the app during the transfer. On iPhones, enable the “Auto Lock Disable” setting in the One Boat Network app to stop the screen from turning off. On Android, keep the screen active.

Format your SD card before copying firmware files to it. Old files on the card can sometimes confuse the update process. Use FAT32 format for the best compatibility with marine electronics.

Troubleshooting Common Update Problems

If your trolling motor does not appear in the app, make sure Bluetooth is enabled on both your phone and the motor. For Minn Kota motors, hold the Pair button until you hear a continuous tone. For Garmin, check that Wi-Fi is active on the motor’s remote control under Settings.

If the download stalls, check your cellular signal strength. Move to an area with better reception or switch to the SD card method instead. A weak signal often causes incomplete downloads that fail during transfer.

If the motor freezes after a failed update, try a power cycle. Disconnect the battery, wait 30 seconds, and reconnect. Some Garmin units support a forced recovery mode where you hold specific buttons during startup to reload firmware from an SD card.

If your One Boat Network app says “No Updates Available” but you know one exists, force close the app and reopen it. Also verify that your trolling motor model is compatible with the app version you have installed.

Best Practices for Future Firmware Updates

Build a simple routine so you never get caught with outdated firmware on the water. Check for updates once a month at home where you have reliable Wi-Fi.

Keep a dedicated microSD card in your tackle box or boat bag. Whenever a new update drops, download it to that card from your computer. Label the card with the date and firmware version so you always know what is on it.

Turn on automatic update notifications in your apps. The One Boat Network app and ActiveCaptain app both send alerts when new firmware is available. These notifications give you time to prepare before your next trip instead of finding out at the ramp.

Save a backup of your motor’s current settings before every update. Some updates reset custom preferences like steering sensitivity, Spot Lock offset, and speed calibration. Having a record makes it easy to restore your preferred setup after the update finishes.

Frequently Asked Questions

Can I update my trolling motor firmware with no internet at all?

Yes. The SD card method requires zero internet at the boat. You download the firmware file at home using a computer with internet access. Then you copy it to an SD card and load it through your fish finder or chartplotter at the boat. This method works for Lowrance Ghost, Garmin Force, and Minn Kota motors paired with compatible display units.

How long does a Bluetooth firmware update take?

Most Bluetooth firmware transfers take between 15 and 30 minutes depending on the file size and your phone model. Keep the app open and both devices powered on during the entire process. Closing the app or letting the phone screen lock can interrupt the transfer and potentially require you to start over.

Will a firmware update erase my saved waypoints and settings?

It depends on the update. Some major firmware updates reset custom settings like steering sensitivity and speed profiles. Saved waypoints stored on your fish finder are usually safe. Check the update release notes on the manufacturer’s website before updating so you know what to expect.

What happens if the update fails halfway through?

A failed update can sometimes leave your motor’s control head unresponsive. Try a full power cycle by disconnecting the battery for 30 seconds. If that does not work, attempt the update again using a different method such as an SD card. Garmin Force motors have a recovery mode that loads firmware from an SD card during startup.

Do I need to update the remote control separately?

For Minn Kota motors, yes. After the control head receives the new firmware, you must update the wireless remote through its own menu under System and then Update Software. Garmin Force remotes and foot pedals update through the same ActiveCaptain app process. Always update the main motor first and the remote second.

Can I use a friend’s phone hotspot to update?

Absolutely. Any phone with a hotspot feature and a cellular data connection will work. Connect your chartplotter or trolling motor to the hotspot network, and it will treat the signal like standard Wi-Fi. Just make sure the hotspot stays active throughout the entire update process.
