I have a 2600 Deere display with SF2 and SF1 AutoTrac activations and a 2630 display with just SF2 AutoTrac. The Deere-ler told me that you need to have both SF1 and SF2 AutoTrac on the display for the RTK to work. Is this the case on the 2600 monitor, or both?. Asking because I'm thinking of moving the activations needed to the newer monitor for planting to take advantage of Guidance features.
