Am a new owner of a 9660 Auto steer ready Deere.  The previous owner took the JD monitor and globe off.  I am trying to decide what would be the best way to utilize the integrated auto steer and yield data.  I already own a Trimble Fmx for guidance in my tractors.  What will it take to integrate this into this Deere model or would I be better going with either a brown box display or a 2600 Deere?  If I go with the FMX will I be able to tie into the JD steering processor or will I need to purchase another Nav ll?  If anyone has these components for sale, let me know.  Email in profile.
