With the auto pilot you have 2 settings for steering control. One uses built in gps to maintain heading and one uses compass heading which I like best and think that's what you have. New spot lock is great. Also you can record up to 6 tracks and gps will follow them. It has cruise control and a couple other options you don't have. To connect to birds you have to have i pilot link for around 700. My opinion is the i pilot is worth the money over copilot having run both.
