Picked up a used 711 c autopilot . Was complete sans the rudder feedback which I bought new. I am removing a working Simrad AP 11 ( 20 years old) that still works fine. Will use the Simrad 80 pump that works :jump fine. Some details ....31 foot 20k pound twin diesel boat. Hynautics K1 steering cylinder (12.1 oz capiticy ) On my boat is a Furuno TZT2 15 inch screen along with a 4 kw dome radar. Nema 2000 backbone for Icom 506 and Furuno 330 gps. The control head connection right to the 7002 understand that. Does the 7002 brain connect to the nema 2000 backbone? Can I just connect the Gp 700 compass now as a stand alone and wait for fall ( cooler weather) the finish the install? Thanks for any help..
