John Deere 770G have it, whether it's an option or standard I don't know. The M series I was on before I "was retired" had it as part of the Cat GPS system. The 2D works without a base station set-up or mushroom poles attached like the 3D uses. It still uses the GPS basics likened to a sat phone. Older systems come up for sale but prices for them is like bidding on "evil buy"
