ive been doing some prototype testing for a aftermarket precision company,for a couple years,and the project manager for this company,used to work for case ih at the large tractor developement center.he said the thing that disgusts him the most about his former employer,is that when the pro 600 came out they had everybody covered,and that they really haven't done anything since,oh came out with a monitor with camera inputs and usb port.weee.
