To expand on this; course and heading are two very different things, and they are very easy for many folks to confuse. Heading is the direction your vessel (bow) is facing, and course is the direction your vessel is moving. Obviously the dynamics are very different in the water (wind, current, sea state etc.) and the direction your vessel is facing is not always the direction its moving.
Autopilot without a GPS input (gyro only) is really a misnomer and not autopilot at all, it is simply auto heading and maintains only the direction which the vessel is facing, not a course. In my opinion, for most recreational boaters, auto heading is a waste of money and a highly risky tool. If you are considering a similar system, spend the money and get a true autopilot system with both gyro and GPS (or even better, multiple GPS) input.
