Failed to mention: You can use this with your existing system, by simply using the 9-pin serial out from EZ-Guide and connect it to a laptop running FarmerGPS.

Also just read your post on the wind direction idea. Very interesting idea! I would not want to make it a 90 degree angle from the AB-lines for 2 reasons: I would want it to work for contour mode as well. 2. Due to field layout you may not be able to create AB-lines which are 90 degress to the wind direction.

HOWEVER your idea should still work by simply providing a wind direction and the software "draws" the implement in that angle, regardless what angle you drive. Would look interesting if you drove in wind-direction, but of course it would actually reflect the real situation... ;-)
