I am looking for a fixed mount gps to interface with my on board laptop
and my auto pilot.

You don't mention what make/model autopilot. That might be the most
important part as many have specific interface requirements.

I am using a Raytheon 3000 autopilot. It works great except for the rudder
sensor. My rudder will turn farther than the sensor will, causing the
threaded attachment rod to pop off.
