GHP 12 Installation Instructions 15Configuring the GHP 12The GHP 12 must be configured and tuned to your boat dynamics.Use the dockside wizard and the sea trial wizard on the GHC 10 toconfigure the GHP 12. These wizards walk you through the necessaryconfiguration steps.Dockside WizardNoticeIf you perform the dockside wizard while your boat is out of the water,provide rudder-movement clearance to avoid damage to the rudder orother objects.You can complete the dockside wizard while your boat is in or out ofthe water. If your boat in the water, it must be stationary while youcomplete the wizard.Performing the Dockside WizardNoticeIf you have a boat with a power assist steering system, turn on thepower assist before performing the dockside wizard to avoid damagingthe steering system.1. Turn on the GHP 12.The first time you turn on the GHP 12, you are prompted tocomplete a short setup sequence on the GHC 10.2. If necessary, complete the setup sequence.3. Start the dockside wizard (page 15).4. Select the vessel type.5. Select the drive unit class (page 15).6. If you have a non-Garmin drive unit, select the drive unit voltage(page 15).7. If you have a non-Garmin drive unit, select the clutch voltage(page 15).8. If you have a solenoid drive unit, select the bypass-valve voltage(page 15).9. If necessary, enable the Shadow Drive (page 15).10. Calibrate the rudder (page 15).11. If you have a non-Garmin drive unit, tune the drive unit (page 16).12. Test the steering direction (page 16).13. If you have a power boat, select the speed source and verify thetachometer (page 16).14. Review the wizard results (page 16).Starting the Dockside Wizard1. After you complete the initial setup, select an option:• If the dockside wizard starts automatically, proceed to step 2.• If the dockside wizard does not start automatically, select Menu> Setup > Dealer Autopilot Configuration > Wizards >Dockside Wizard.2. Select Begin.Selecting the Drive unit Class• 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 have a solenoid drive unit, select Solenoid.• If you have a non-Garmin drive unit, select Other.Selecting the Drive unit VoltageNoticeProviding an incorrect drive-unit-voltage value for your non-Garmindrive unit can damage your drive unit.NOTE: This setting applies only to non-Garmin (other) drive units.1. Consult the manufacturer of your non-Garmin drive unit todetermine the drive-unit voltage.2. Select the voltage approved for your drive-unit motor.Selecting the Clutch VoltageNoticeProviding an incorrect clutch-voltage value for your non-Garmin driveunit can damage your drive unit.NOTE: This setting applies only to non-Garmin (other) drive units.1. Consult the manufacturer of your non-Garmin drive unit todetermine the drive-unit-clutch voltage.2. Select the voltage approved for your drive-unit clutch.Selecting the Solenoid VoltageNoticeProviding an incorrect drive-unit-voltage value for your non-Garmindrive unit can damage your drive unit.NOTE: This setting applies only to non-Garmin solenoid drive units.1. Consult the manufacturer of your non-Garmin solenoid drive unit todetermine the drive-unit voltage.2. Select the voltage approved for your solenoid drive-unit.Selecting the Bypass Valve VoltageNOTE: This setting applies only to non-Garmin solenoid drive units.1. Consult the manufacturer of your non-Garmin solenoid drive unit todetermine the bypass-valve voltage.2. Select the voltage approved for your solenoid bypass valve.Enabling Shadow DriveIf you installed the GHP 12 on a boat with a hydraulic steering system,you can install a Garmin Shadow Drive device (sold separately -page 3).• Select No if you did not install a Shadow Drive device.• Select Yes if you installed a Shadow Drive device (page 6).Calibrating the RudderNOTE: If an error appears during these steps, the rudder feedbacksensor may have reached its limit. Make sure the feedback sensor hasbeen installed correctly. If the problem persists, bypass this error bymoving the rudder to the farthest position that does not report an error.1. Position the rudder so that the boat would steer fully starboard andselect OK.2. After the starboard calibration is complete, position the rudder sothat the boat would steer fully port and select OK.3. After the port calibration is complete, center the rudder position, letgo, and select Begin.The autopilot will take control of the rudder.4. Wait while the autopilot calibrates the rudder.5. Select an option:• If the calibration completed successfully, select OK.• If the calibration did not complete successfully, repeat steps 1–4.
