I'm planning on putting in an autopilot over the winter and am leaning towards the Simrad WP32. However, from the posts in these and other forums, it appears the WP32 may not be able to interface with Garmin GPS units. Since I have a Garmin 192C on my boat, this would be a major drawback to the Simrad unit. Anyone have any luck with interfacing this unit to a Garmin GPS? If the answer is yes, I'd appreciate feedback on what it takes to do so. Thanks.
