I have a boat with seastar optimus steering installed but no joystick. What is the difference between the NAVPILOT 300-OPT, and the NAVPILOT 300? I love the SCX20 and would like to do that with the NavPilot 300 but if I need to buy the OPT version I will just use the PG700. The pictures make the difference look like a couple a maretron Canbus connectors but I haven't found a parts list.
