R series tractors with the 4600 have the USB port either in the armrest or in the console, the 4640 has the USB in the side similar to the 2630, wifi is not needed at all to operate the displays, Raw data is exported just like it always has, RX maps are fully functional and have been for some time, Have no timeline on the full functionality but was told by the end of 2018, really all that is left is Machine Sync Combine/Grain Cart automation.
