I want to replace my old robertson autopilot
with a raymarine
.its still working good but is very old and it doesnt give me any rudder
reference. I have a new garmin
4012 and i would like to interface it with the the raymarine
unit is it possible to use the heading sensor info for marpa tracking. I am also a bit confused about which system to buy I want to use the existing canada
metal octupus ram and robertson pump.do I need the x-sol core
pack? Thanks to anyone who can give me some advice.
