I installed the Agra-GPS Bridge in our MT865C a couple weeks ago. Steering with a GS3 2630. It steered pretty darn good right out of the box using it for anhydrous application at 5-6mph but this week we're plowing tile at 1mph and I can't get it to stop wiggling. I've tried every combination of settings and I just can't get it where I want at the slow speed. Is that just the nature of the Challenger steering systemn or can someone recommended any settings? It previously had a Trimble CFX-750 and using Deere to steer it is a big upgrade. Thanks.
