Have you looked at Farmscan?

It can be setup with mapping, autosteer, variable rate control, auto boom shutoff, etc.

You can start with a basic system and add on,
or get a package deal that includes what you want most.


The 4000 and 5500 can map and autosteer round and round.

You can add autoboom with rate control for $2000


I used the 5500 in Texas last spring, here is an actual map of one of the fields:
