To add an Insite you need some cabling from AG leader that just taps into the yield monitor system on the combine directly at the sensors. It will not talk directly to the combine electronics. The Intelleview and the Intelleview Plus can be plugged directly into the CAN bus connector. The combine needs the latest level software on it and the Intelleview needs to be loaded with matching software. The Intelleview 2 is a color screen. The Intelleview Plus 2 is also color but a touchscreen. (Intelleview and Intelleview Plus are BandW) If you are thinking of buying new go with the color displays. You do not need the touchscreen for this combine but it is slightly larger. For NH products the touchscreen is only required to run the SP series planter. All other equipment can get by with the cheaper color screen or most of the older BandW screens. If you look at BandW, the only version of the large BandW touchscreen that will work in the combine has only ONE card slot on it. If it has 2 card slots then it won't work on the NH combine.
