Place the sensor in the chosen mounting location, and mark
the center of the three mounting holes.
3
Place the tiller-arm mount on the tiller arm in the chosen
location, and mark the center of the two mounting holes.
4
Using a

in. (3.2 mm) bit, drill three pilot holes on the
mounting surface for the sensor, and two pilot holes on the
tiller arm for the tiller-arm mount.
5
Fasten one of the ball-joint assemblies to the tiller-arm
mount, using the included M6 locknut.
6
Place the other ball-joint assembly into the appropriate hole
on the sensor (typically the second hole from the tip), and
fasten it with the included washer and locknut, using a 10
mm socket.
7
Tighten the ball-joint assemblies using a 8 mm wrench at the
base.
8
Fasten the sensor to the mounting surface using the included
screws.
9
With the rudder amidships and the sensor at center position,
measure the distance from the ball-joint assembly on the
sensor to the location where you plan to attach the tiller-arm
mount to the tiller arm.
10
If the threaded rod is too long, you must cut it to the correct
).
11
Thread both of the standard M6 nuts onto the threaded rod.
12
Thread the rod into the ball-joint assembly connected to the
sensor.
13
Thread the other end of the rod into the ball-joint assembly
connected to the tiller-arm mount.
14
Fasten the tiller-arm mount to the tiller using the included
screws.
15
Tighten the M6 nuts on the threaded rod against both of the
ball-joint assemblies.
Cutting the Threaded Rod
If the included threaded rod is too long for your chosen
installation location, you must cut it.
1
Thread one of the included standard M6 nuts onto the
threaded rod.
Do not use one of the included M6 locknuts.
2
Measure and mark the threaded rod with electrical tape.
3
Using the appropriate saw, cut the threaded rod at the
marked location.
4
Remove the nut from the threaded rod, turning it counter-
clockwise over the cut area.
The nut should straighten any threads that may have been
damaged while cutting the rod.
Connecting the Device to the Autopilot System
1
Route the cable from the sensor to the orange 12-pin
connector on the ECU of the autopilot system.
The installation instructions provided with your autopilot
system will help you identify where this connector is located.
If needed, extension cables are available.
2
Connect the sensor to the autopilot system.
Configuring the Sensor
When connected to a Garmin autopilot system, the sensor is
configured using the autopilot helm control.
NOTE:
If an error appears during these steps, the sensor may
have reached the limit of its movement range. Make sure the
sensor was installed correctly. If the problem persists, bypass
this error by moving the rudder to the farthest position that does
not report an error.
1
Enter Dealer Mode by following the procedures in your
autopilot installation instructions.
