CNH charges the dealer an arm and a leg for the PC software, hardware, and the various and sundry firmware upgrades and unlocks, I've been told. The dealer can do what he wants with them after that, as far as helping their customers. One of our local dealers figures there's no way they'll ever recoup their money CNH charges them by selling the individual updates and unlocks to farmers, so they just do it for their customers for just the cost of the time knowing good will is worth a lot. They budget in the cost of the software in their operations I suppose. Anyway I thought that was really good of them. I was able to get everything needed for variable rate seeding on my new holland air drill. He had software updates and unlocks for red, yellow, and blue machines. Just had to take him the monitor.CNH does not charge an unlock for isobus. It does charge for variable rate or sectional control through the virtual terminal. Maybe your dealer is confused as to what you actually want?
