A 7″ Android display for the helm or the chart table. Run the Nauti-Control app on it for live instruments and autopilot control from your Nauti-Control controller, and your chart apps (Navionics, Savvy Navvy, OpenCPN) alongside. It’s wired into the boat’s 12 V or 24 V supply, so it’s always on the helm and your phone stays in your pocket.

Your instruments and autopilot at the helm

The Nauti-Control app connects to your controller over Bluetooth and shows heading, depth, wind, boat speed, course and rudder on a dashboard you arrange yourself. The autopilot page gives you Standby, Auto, Wind, Track and 1° / 10° course changes, where your pilot supports those modes.

Your chart apps on the same screen

The M22 runs Android with the Google Play Store, so you can install the navigation apps you already use, including Navionics, Savvy Navvy and OpenCPN. Each needs its own account or charts.

Questions

Do I need a Nauti-Control controller?
For instruments and autopilot control in the Nauti-Control app, yes. The controller sends the boat data and the M22 shows it. Chart apps such as Navionics work on their own.

Is it waterproof?
Yes, the display is IP67, so it’s fine in the cockpit. Keep the power converter and cable joints somewhere dry, such as behind a bulkhead or in a locker.

Does it have a battery?
No. It runs off the boat’s supply and switches off with its breaker.

What warranty does it have?
12 months against manufacturing defects, return to base (see our terms). For help or a return, email admin@nauti-control.com.

The M22 and Nauti-Control are supplementary aids, not safety-critical navigation equipment. The skipper stays responsible: keep a proper lookout.
