The Dockside Wizard
If you perform the Dockside Wizardwhile your boat is out of the
water, provide rudder-movement clearance to avoid damage to
the rudder or other objects.
You can complete the Dockside Wizard while the boat is in or
out of the water.
If the boat is in the water, it must be stationary while you
complete the wizard.
Performing the Dockside Wizard
1
Turn on the autopilot.
The first time you turn on the autopilot, you are prompted to
complete a short setup sequence.
2
If the Dockside Wizard does not start automatically after the
setup sequence, select Menu > Setup > Dealer Autopilot
Configuration > Wizards > Dockside Wizard.
3
Select the vessel type.
4
If necessary, calibrate the rudder sensor.
5
Test the steering direction
6
If necessary, select the speed source
7
If necessary, verify the tachometer
8 Test the helm lock-to-lock.

Review the wizard results
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
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
Select an option:
• If you connected a NMEA 2000-compatible engine (or
engines) to the NMEA 2000 network, select NMEA 2000.
• If a NMEA 2000 tachometer data is unavailable 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 NMEA 2000 or using a GPS device
as the speed source.
Verifying the Tachometer
This procedure does not appear if GPS or None is selected as
the speed source.
1
With the engine (or engines) running, compare the RPM
readings on the helm control with the tachometer (or
tachometers) on the dashboard of your boat.
2
If necessary, adjust the readings on the helm control until
they match the tachometer (or tachometers) on your boat.
Reviewing the Results of the Dockside Wizard
The helm control displays the values you chose when you ran
the Dockside Wizard.

The Sea Trial Wizard
The Sea Trial Wizard configures the fundamental sensors on
the autopilot, and it is extremely important to complete the
wizard in conditions appropriate for your boat.
Important Sea Trial Wizard Considerations
The Sea Trial Wizard must be completed in calm water.
Because the nature of calm water is relative to the size and
shape of the boat, before you begin the Sea Trial Wizard, the
boat must be in an appropriate location:
• The boat must not rock while sitting still or moving very
slowly.
• The boat must not be significantly affected by the wind.
While completing the Sea Trial Wizard, observe these
considerations:
• Weight on the boat must remain balanced. While completing
any of the steps in the Sea Trial Wizard, do not move around
on the boat.
• On sailboats, the sails must be lowered.
• On sailboats, the motor must remain in a position that drives
the boat in a straight direction.
Performing the Sea Trial Wizard
1
Drive your boat to an open area of calm water.
2
Select Menu > Setup > Dealer Autopilot Configuration >
Wizards > Sea Trial Wizard.
3
If necessary, configure the planing RPM.
This step applies only to planing-hull power boats with the
speed source set to None.
4
If necessary, configure the planing speed.
This step applies only to planing-hull power boats with the
speed source set to GPS.
5 If necessary, configure the high RPM limit.
This step applies only to power boats with the speed source
set to GPS.
6
If necessary, configure the maximum speed.
This step applies only to power boats with the speed source
set to GPS.
7
Calibrate the compass
8
Perform the autotune procedure
9
Set north (page 16).
10 If necessary, set the fine heading adjustment
Calibrating the Compass
1
Drive your boat at cruising speed in a straight line.
2
Select an option:
• If you are performing this procedure as part of the Sea
Trial Wizard, select Begin, and continue to drive in a
straight line.
• If you are performing this calibration outside of the Sea
Trial Wizard, from the heading screen, select Menu >
Setup > Dealer Autopilot Configuration > Automated
Setup > Calibrate Compass > Begin.
3
When instructed, turn the boat clockwise slowly until
calibration is complete, taking care to make the turn as
steady and flat as possible.
The boat should not list during calibration.
4
Select an option:
• If the calibration completes successfully, select Done.
• If the calibration fails, select Retry and repeat steps 1–3.
