You need a second receiver on the implement for autopath to work on your planting or strip till pass. Just having RTK on a 2630 is not like autopath at all. The second receiver does not need any activations, it can be just SF1 and share the better signal off the one on the cab. 

You will need the exact same specs to run the passive implement guidance as you need to run autopath, so you might as well run it to get best performance. It's just a toggle on the screen at that point for on/off. 

I'd not really trust an ATU to do turn automation if it will even let you do it.
