Is installation difficult? Does it require professional installation?

Installation complexity varies depending on your boat's existing steering setup and below-deck configuration. While experienced sailors and riggers often handle drive unit installations themselves, Garmin recommends working with a qualified marine technician to ensure the unit is correctly fitted, aligned, and wired for safe autopilot operation. Always refer to the installation manual for detailed guidance.
