| What is the difference between a Nav 2 and a Nav 3? I have retrofitted two Fendt tractors with a hydraulic autopilot. One has a Nav 2, the other a Nav 3. I know that the Nav 3 can control a third coil, but what does that mean exactly? Why is a third coil needed? Then there are also Rev C, D, H, K...etc. Is there still different hardware? One last question: One of the two autopilots (GFX 750, Nav 2, H3 valve) has the Autosense. The other autopilot system (GFX 750, Nav 3, H3 valve) has an IMD 900 steering angle sensor. Can the same steering performance be expected from the Autosense? And can it be problematic if the Nav controller is mounted at an angle in the cab on one system?
