Reactor™ 40 Mechanical/Retrofit/Solenoid Corepack without GHC™ 20

The Most Responsive Autopilot System on the Water

  • Solid-state 9-axis Attitude Heading Reference System (AHRS)
  • Minimizes heading error, course deviation, rudder movement and power consumption while providing a comfortable ride
  • Minimal commissioning and calibration
  • Supports heading hold, wind hold, step turns and tack/jibe modes

With a complete package designed for powerboats and sailboats, Garmin brings an advanced marine technology to the boating public that was once only available for commercial boats. The Reactor 40 autopilot series is simply the most responsive autopilot system we have ever offered.

Reactor 40 autopilots are very versatile. Both powerboat and sailing features are available in all corepacks, including heading hold, wind hold, tack/jibe, step turns and more; simply pick the autopilot that’s compatible with your existing steering system. If you don’t see a compatible Reactor 40, you’ll find the Reactor 40 mechanical/retrofit/solenoid is compatible with a wide variety of steering systems, whether hydraulic, cable drive, mechanical and solenoid. Just pair GRF™ 10 with your drive system already on board.

The Reactor 40 mechanical/retrofit/solenoid autopilot corepack is ideal for sailboats and powerboats with direct or cable-actuated steering systems. This Reactor 40 below-deck autopilot system gives captains that “extra set of hands” they need so you can safely attend to your sails, lines, winches and radios, without worry. With its solid-state 9-axis AHRS, Reactor 40 mounts anywhere, in any orientation and requires minimal commissioning.

Solid-state 9-axis AHRS

With its advanced solid-state 9-axis AHRS, you can mount Reactor 40 nearly anywhere, in any orientation. In addition, this new system greatly minimizes heading error, course deviation, rudder movement and power consumption while providing a comfortable ride for all on board.

Reacts to Conditions

This amazing autopilot actually reacts to the sea to hold your course. Even when the boat is pitching and rolling, you can remain confident that the Reactor 40 autopilot will keep you on your desired course.

Minimal Commissioning and Calibration

All autopilots require commissioning and calibration — all of them. We know you just want to get on the water, so we made this process as fast and easy as possible. That’s the power of simple.

Full Integration with Garmin Chartplotters

Combined with a compatible Garmin networked chartplotter, you can have full control of Reactor 40 from wherever you are on the boat. In addition to holding its course in virtually all weather and wind conditions, the system can smoothly perform a variety of preprogrammed trolling and search procedures. Plus, with a compatible Garmin networked chartplotter and BlueChart® g2 Vision® charts (sold separately), you gain optional features such as Auto Guidance¹, which automatically steers GPS paths.

Stay in Control with Shadow Drive™ Technology

On hydraulic installations, the Reactor 40 mechanical/retrofit/solenoid autopilot corepack can add optional patented Shadow Drive technology. This gives you the security of knowing you maintain control, even when the autopilot is engaged. The Shadow Drive system automatically disengages the autopilot if the helm is turned, giving you the freedom to maneuver the boat. The autopilot automatically re-engages when you hold a steady course.

Choose from 3 Class Drives

Reactor 40 is available with 3 linear drives (sold separately) capable of driving many different steering systems on most midsize to large vessels (depending on the particular installation). All Garmin linear drives include built-in rudder feedback sensing.

  • Class A Drive Unit — up to 28,500 lbs of displacement
  • Class B Compact Drive Unit — up to 48,400 lbs of displacement
  • Class B Drive Unit — up to 79,000 lbs of displacement

Add Even More Peace of Mind

Add an optional GRF 10 rudder feedback sensor, and you can further enhance the performance of your Reactor 40 autopilot.

Well designed, secure hold
Style: MagSafe Car Phone Holder, Style: MagSafe Car Phone Holder
This Tesla screen phone mount feels well designed and has a strong MagSafe magnet to hold your phone. It is meant for the newer generation of Teslas with the screen that sits out from the instrument panel. It’s sits on the corner and has padding to keep it from scratching the screen. The size of the grippers keeps them right at the edge of the bevel so it doesn’t block any portion of the screen. They are easily tightened with a rotating dial that doesn’t slip. The MagSafe magnet can be positioned in a variety of positions. The kit comes with an adhesive metal ring in case your phone or case isn’t MagSafe compatible. Unfortunately, it didn’t come with any instructions, but it was easy enough to figure out.

Mount your MagSafe compatible phone to the Tesla monitor
Style: MagSafe Car Phone Holder
The Tesla MagSafe monitor mount fits the screen of a Model 3 perfectly. It has a strong magnet and when you attach it to the monitor and tighten the wheels this mount stays put. I can now have my phone docked next to the monitor in front of the steering wheel, which really helps me unlock the phone when I need to access things like my phone's calendar or emails. I can also use the phone as a music switching interface when it's connected to the car via bluetooth. The design of the mount is very simple, it has two cushioned clamps, I never felt like I was compressing the clamps too hard that it'll crack the screen but I just adjusted it enough so it won't fall down with the weight of the phone on the mount. The magnet of the mount is very strong and as long as your phone supports MagSafe docking it will not have a risk of falling when you drive even over bumps. The arm of the mount is adjustable so you can place it at the appropriate angle that you like.

Good phone mount
Style: MagSafe Car Phone Holder, Style: MagSafe Car Phone Holder
So far I’m very happy with the phone mount for my Tesla Model 3. It installed very easy, feels secure, the magnetic ring holds my iPhone really well. My last mount had an issue with staying in place, the phone would often tilt when going over bumps but this one seems solid. There were no installation instructions but it was a no brainer to install. Like most mounts the give you a separate metal ring you can attach to the back of your phone if your phone or case isn’t MagSafe.

Made of alloy and mostly plastic
Style: MagSafe Car Phone Holder, Style: MagSafe Car Phone Holder
This is a fairly decent MagSafe mount that attaches cleanly to an LCD car display. It works and looks good on my Tesla Model 3. The only part that is metal is the bracket but the rest seems to be made from a metallic looking plastic. I do like that the inside of the clamps can be adjusted independently and there’s a layer of silicone padding to protect the screen. I was able to make it pretty tight with no movement at all. It only works well on a “naked” phone or a cover that has MagSafe ring built in. I have a super thin case and it seems to hold pretty well so far but I do wish the magnets were a bit stronger. The good thing is that it uses a standard ball joint so I have other types of mounts that could easily fit in place of the MagSafe version. The only other thing that I think detracts from the overall “clean look” is the screened text on the clamp that simply says “Screen Holder”. It would have been better not there.

EXCELLENT Product for using with the dash mount BUT not so good for all cars with the vent mount.
This is a great product for wireless phones worked perfectly for my SG S21 the mount is really good sturdy flexible and firm if done right. BUT the vent jack plug is short for my Camry 2018 doesn't hold the phone firmly. It keeps wobbling when driving. So if you're looking for using just the vent holder make sure your car has a short AC flap so it can mount the plug firmly hold the phone properly. The phone holder is amazing it works really good just the way it is shown in the description. So guys first check the flap size of your cars AC vent must be short if you're looking to use the Vent plug holder. But if you're going to use it only with the dash mount its fantastic and holds the phone really firm and good. I really love this product and highly recommend to buy.
