Selecting the Drive Unit Class
On the helm control, select an option:
• If you installed a Garmin Class A drive unit, select
Class
A
.
• If you installed a Garmin Class B drive unit, select
Class
B
.
• If you connected the autopilot to an existing solenoid drive
unit, select
Solenoid
.
• If you connected the autopilot to an existing drive unit not
sold by Garmin, select
Other
.
Selecting the Drive-Unit Voltage and Drive-Unit-Clutch
Voltage
NOTICE
Providing an incorrect drive-unit-voltage value or drive-unit-
clutch-voltage value for your drive unit can damage your drive
unit.
These settings apply only to drive units not sold by Garmin.
1
Consult the manufacturer of your drive unit to determine the
drive-unit voltage and drive-unit clutch voltage.
2
On the helm control, select the voltage approved for your
drive unit.
3
Select the voltage approved for your drive-unit clutch.
Selecting the Solenoid Voltage and Solenoid Bypass-Valve
Voltage
NOTICE
Providing an incorrect solenoid-voltage value or solenoid-
bypass-valve-voltage value for your drive unit can damage your
drive unit.
These settings apply only to solenoid-type drive units.
1
Consult the manufacturer of your solenoid drive unit to
determine the solenoid voltage and the solenoid bypass-
valve voltage.
2
On the helm control, select the voltage approved for your
solenoid drive unit.
3
Select the bypass-valve voltage approved for your solenoid
drive unit.
Calibrating the Rudder
NOTE:
If an error appears during these steps, the rudder
feedback sensor may have reached its limit. If this happens, the
rudder feedback sensor may not have been installed correctly. If
the problem persists, you can continue with calibration by
moving the rudder to the farthest position that does not report an
error.
1
Position the rudder so that the boat would steer fully
starboard and select
OK
.
2
After the starboard calibration is complete, position the
rudder so that the boat would steer fully port, and select
OK
.
3
After the port calibration is complete, center the rudder
position, let go, and select
Begin
.
The autopilot takes control of the rudder.
4
Without touching the rudder or helm control, allow the
autopilot to calibrate the rudder.
5
Select an option:
• If the calibration did not complete successfully, repeat
steps 1 through 4.
• If the calibration completed successfully, select
OK
.
Enabling the Shadow Drive
If you installed the autopilot on a boat with a hydraulic steering
system, you can install a Garmin Shadow Drive valve (sold
separately).
On the helm control, select an option:
• Select
No
if you did not install a Shadow Drive valve.
• Select
Yes
if you installed a Shadow Drive valve.
Tuning an Existing Drive Unit
NOTE:
This process does not apply to solenoid drive units.
If you connected the autopilot to a drive unit not sold by Garmin,
you must tune the drive unit for use with the autopilot system.
1
Center the rudder position and let go of the helm.
2
On the helm control, select
Continue
.
The autopilot takes control of the rudder as it tunes the drive
unit. A message appears on the helm control when the tuning
is complete.
3
After the tuning is complete, select an option:
• If the tuning completes successfully, select
Done
.
• If the tuning is not successful, repeat steps 1 through 3.
NOTE:
If needed, you can refine the tuning later, using the
advanced settings (
Performing Advanced Tuning Procedures
).
Testing the Steering Direction
1
Test the steering direction.
When you select
, the rudder must turn so that the boat
steers to the left, and when you select
, the rudder must
turn so that the boat steers to the right.
2
Select
Continue
.
3
Select an option:
• If the steering test turns the boat in the correct direction,
select
Yes
.
• If the steering test turns the boat in the opposite direction,
select
No
.
4
If you selected
No
in step 3, repeat steps 1–2.
Selecting the Speed Source
NOTE:
This procedure applies only to power planing hull and
power displacement hull vessels. It does not appear when
configuring the autopilot for a sailboat.
Select an option:
• If you connected a NMEA 2000 compatible engine (or
engines) to the NMEA 2000 network, select
Tach - N2K
or Proprietary
.
• If NMEA 2000 tachometer data source is not available or
unusable, select
GPS
as a speed source.
• If you did not connect a NMEA 2000 tachometer or GPS
device as a speed source, select
None
.
NOTE:
If the autopilot does not perform well using
None
as the speed source, Garmin recommends connecting a
tachometer through the NMEA 2000 network or using a
GPS device as the speed source.
Verifying the Tachometer
This procedure applies only to power planing hull and power
displacement hull vessels. It does not appear when configuring
the autopilot for a sailboat.
This procedure does not appear when GPS or None is selected
as the speed source.
