You can purchase a customer version of it but it's not cheap, its up to the dealer if they want to offer it, and even then it has to be approved by Deere. I believe $195 per month plus the cost of the EDL tool used to connect ($1400ish?). You get access to service manuals, read codes, and can do calibrations but no controller programming. The monthly fee is only for one division, i.e. Ag and Turf OR construction and forestry, not both. And you have to go through the coresponding dealer (Ag through Ag dealer, C+F through C+F dealer).
