We have a TG 305 that is autosteer ready and a 9570 that is equipped as well.  The previous owner used a trimble unit in the tractor and we current have agleader which we unfortunately did not do the steering unlock.  As for the combine we currently use the neighbors JD 2600 just to steer the combine and run the insight for our monitor.  We would like to have one unit do both in the tractor and combine, but not sure which route.  Will be keeping the insight either way to use in other tractor as a spray and nitrogen controller.  Don't really want to spend the $20,000 on the intergra and paradyme but maybe should?
