I've got an AG3000 receiver that has stopped seeing satellites after an update. This is beyond the local dealer’s repair capabilities, they have kindly loaned me another to keep me going. Just looking for opinions on the best way forward. The receiver runs a steer ready isobus MF6616 through a data 4 screen. I would like a new hardware solution to be transferable to an as yet non-steer ready, isobus MF 6718S with a field star 5 screen.
