Nauti-Control firmware version 3.2.0 is now available for both SeaTalk and N2K controllers. This release mainly improves B&G / Navico NAC autopilot control and also includes the SeaTalk reliability and restart improvements from V3.1.1.

What’s Changed

B&G / Navico NAC Autopilots

• Fixed an issue where selecting Auto on some B&G NAC autopilot computers could lock onto an incorrect heading.
• Updated mode commands to match the command format used by B&G / Navico MFDs.
• Auto now selects compass heading hold.
• Standby disengages the autopilot.
• Wind selects apparent wind mode.
• Track selects GPS route / navigation mode.
• Tack sends the B&G Tack / Gybe command.
• ±1° and ±10° course changes are unchanged.

Wind, Track and Tack

• Wind: Requires the autopilot system to be configured as a sailboat.
• Track: Requires an active route on the chartplotter.
• Tack / Gybe: Requires Wind mode to be active. Gybe also requires Gybe Inhibit to be set to Allow Gybe.

SeaTalk Improvements

• Fixed the SeaTalk keepalive so incoming SeaTalk data starts correctly without needing an RF remote button press.
• Improved controller restart handling.
• Bluetooth and Wi-Fi now shut down cleanly before the controller restarts.

How to Update

Choose the update method that matches the firmware version currently installed on your controller.

Currently Below Firmware V3.0 — USB Web Flasher Required

OTA updating is not available on older firmware versions. Controllers running firmware below V3.0 must first be updated over USB using the Nauti-Control Firmware Flasher.

1. Open the Nauti-Control Firmware Flasher using Google Chrome.
2. Connect the controller using a USB data cable.
3. Select and flash the correct complete image for your controller: SeaTalk or N2K.

After updating to V3.0 or newer, future firmware and filesystem updates can be installed using the OTA method.

Currently on Firmware V3.0 or Newer — OTA Update

Controllers already running firmware V3.0 or newer can be updated over Wi-Fi from the controller’s web interface.

1. Connect your phone, tablet or computer to the Nauti-Control Wi-Fi network.
2. Open the controller web interface in your browser. When connected directly to the controller this is normally http://192.168.1.1.
3. Open the Update page.
4. Upload the firmware file for your controller.
5. Wait for the update to complete and for the controller to restart.
6. If the filesystem is shown as out of date, upload filesystem-v3.2.0.bin.

Firmware Files

• N2K Wireless: firmware-v3.2.0-n2k.bin
• ST Wireless: firmware-v3.2.0-seatalk.bin
• Filesystem: filesystem-v3.2.0.bin

Important Notes

• Make sure you install the correct firmware for your controller type.
• Do not install SeaTalk firmware on an N2K controller or N2K firmware on a SeaTalk controller.
• If the Update page reports that the filesystem is out of date, install the V3.2.0 filesystem package.
• V3.2.0 is particularly recommended for users with B&G NAC autopilot systems.
