If you set this value too high, the autopilot may be
overactive and attempt to constantly adjust the heading at
the slightest deviation. An overactive autopilot can drain
the battery at a faster-than-normal rate.
• If you have a planing-hull powerboat with the speed
source set to
Tach - N2K or Proprietary
or
GPS
, select
Low Speed Counter
or
High Speed Counter
to adjust
how tightly the rudder corrects the turn overshoot.
If you set this value too low, the autopilot can overshoot
the turn again when it attempts to counter the original turn.

Advanced Configuration
Advanced configuration options are not available on the helm
control under normal conditions. To access the advanced
configuration settings of the autopilot, you must first enable

After you reset the drive-unit settings to the default values,
you must perform the
Generic Tune

If you adjust any of these values or run any of these tuning
procedures, you must perform the autotune procedure again.
Performing Advanced Tuning Procedures for an Existing
Drive Unit
NOTICE
You should perform these procedures only if you completely
understand the concepts of drive-unit speed and error tolerance
as defined below. Incorrectly setting these values can damage
your drive unit, drain your battery at a faster-than-normal rate, or
result in poor autopilot performance.
For almost every installation of a drive unit not sold by Garmin,
the generic tuning procedure performed during the Dockside
Wizard is sufficient to calibrate the drive unit for use with the
autopilot system. Use these advanced-tuning procedures only
when you need to make slight adjustments to the performance
of the drive unit.
Tuning the Speed on an Existing Drive Unit
This setting does not apply to solenoid drive units.
The speed of the drive unit determines how quickly it reacts to
commands from the autopilot.
If you set the speed value too low, the drive unit appears slow
and takes a long time to respond to commands from the
autopilot.
If you set the speed value too high, the drive unit reacts too
quickly and can force the rudder to the stops at a high rate of
speed. This could damage the drive unit or rudder stops and
drain your battery at a faster-than-normal speed.
