I work at a Deere dealership and we were talking about this today. If you get the program you can troubleshoot codes and link with your equipment. That is about all you can do. You unfortunately cannot do any programming or say if you replace a sensor that went bad, you cannot adjust anything in any way on your machine. Even though your machine belongs to you, the computer technology belongs to Deere. In my opinion, it is a waste of your money.
