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.
NOTE: If it is incorrect, the steering direction can also be changed
during the autotune procedure
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 you did not connect a NMEA 2000-compatible engine (or
engines), select the engine (or engines) to which you connected
the tachometer sensor from the CCU.
◦ For a single-engine boat, select Port.
• If tachometer data is unavailable or unusable, select GPS data as
a speed source.
◦ When GPS data is used as a speed source, the maximum
speed for all vessel types must be configured.
• If you did not connect a speed source, select None.
◦ If the autopilot does not perform well using None as the
speed source, Garmin recommends connecting a tachometer
or GPS 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 GHC 10 with the tachometer (or tachometers) on the dashboard
of your boat.
2. If the values do not match, use the arrows to adjust the Pulses Per
Rev values.
NOTE: When you adjust the Pulses Per Rev with the arrows, there
is a delay before the new RPM readings appear on the GHC 10.
Ensure you wait until the GHC 10 adjusts to the new reading for
each adjustment.
Reviewing the Results of the Dockside Wizard
The GHC 10 displays the values you chose when you ran the Dockside
Wizard.
1. Examine the results of the Dockside Wizard.
2. Select any incorrect value and select Select.
3. Correct the value.
4. Repeat steps 2 and 3 for all incorrect values.
5. When you are finished reviewing the values, select Done.
about 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
Complete the Sea Trial Wizard in calm water. The nature of calm water
is relative to the size and shape of your boat.
• Ensure your boat does not rock while sitting still or moving very
slowly.

• Ensure your boat is not significantly affected by the wind.
• Keep the weight on your boat balanced. DO NOT move around
on the boat while completing any of the steps in the Sea Trial
Wizard.

Configuring the Planing RPM
NOTE: This procedure does not appear if you select displacement hull
as your vessel type, or if you select None as the speed source.
1. Note the RPM reading from the tachometer on the dashboard of
your boat at the point your boat transitions from displacement to
planing speed.
2. If the tachometer value does not match the value on the GHC 10,
use the arrows to adjust the value.
3. Select Done.
