How to Connect Navionics Boating to Your Boat’s GPS and Depth with Nauti-Control

The Navionics Boating app can use your boat’s own GPS position, speed and depth instead of your phone’s. It reads them over Wi-Fi from an NMEA 0183 device, and the Nauti-Control controller (N2K Wireless or ST Wireless) works as one. Here’s how to connect it.

What You Need

• A Nauti-Control N2K Wireless or ST Wireless controller on your boat’s network.
• The Navionics Boating app on your phone or tablet, with charts downloaded for your area.

1. Join the Controller’s Wi-Fi

Connect your phone or tablet to the controller’s Wi-Fi network. Android may say “No internet access”; that’s expected. Download your Navionics maps (Menu, Download Maps) before you leave, so they work offline.

2. Add the Controller in Navionics

1. Open Menu and choose Paired Devices.
2. Under “Not working? Try manually adding your NMEA 0183 Wi-Fi device”, tap Add Device.
3. Name: anything, for example Nauti-Control.
4. Host: 192.168.1.1
5. Port Number: 8091
6. Keep TCP selected and tap Save.

3. Check It’s Connected

Paired Devices now shows the controller as Connected, with Sonar: Receiving data (depth) and External GPS: Receiving data.

Close the menu and tap the locate button. Your boat shows at your own GPS position, with speed over ground and depth on the chart.

Good to Know

• On our test bench Navionics used position, speed, course and depth. It has no wind or heading display, so for those, and for your autopilot, run the Nauti-Control app alongside it. On an Android tablet or the M22 display you can use split screen.
• If the controller is joined to your boat’s own Wi-Fi router, use the address your router gave it instead of 192.168.1.1. The port is still 8091.

Navionics is a Garmin brand and is not connected with Nauti-Control. Nauti-Control is a supplementary aid, not a replacement for your chartplotter or a proper lookout.
