This is my 2nd request, so please ignore if you've already seen this message. Harry, thanks so much for trying so hard for us.
Basically, we have the Raymarine
ST6000+ auto pilot for a tiller. Everything works except the head
control unit. The new ones have a different wiring
system and work through a computer. We don't have a computer with our system and don't really want one. So, to replace new we have to buy a load of expensive stuff we don't need or want.
It is quite an old model so I've attached a photo
of the back of our control unit. If you have one of these lying around and would be willing to sell, then please do get in touch.
Thanks so much
