You'll need the keycard and mobile processor if you're running the old "brown box" display or you'll need an unlock code if you have a GS2. Trimble charges more for the "Autopilot" while Deere charges more for the activations and less for the equipment. As I've said before we've priced them and a full integrated Deere system usually runs within a few hundred dollars of a Trimble.

I guess to me it would depend on what your future plans are. Do you plan on getting the Deere head guidance or the headsight? Are you going to be able to use the Deere globe to steer a tractor in the future?
