[CA] ST5000+ Autopilot

[Bass]

Chuck - I have purchased the S100 and interfaced it to the autopilot. It operates on standby and auto but no course correction but reading this forum I need to set the S100 to powerboat and will try that today. I have 2 questions:
1- Connecting ST5000+ to C95 - The ST5000+ is in my electronics box under top and the C95 I am connecting it too (via seatalk - seatalk converter bus) is on the console and the cable provided is only 3 feet and will not reach the head unit. The cable is A22164. I cannot find in any of the literature how to extend this cable or purchase a longer one I need about 6'. Please advise.
2- What functionality can I expect once the ST5000+ is connected to the C95? Assume I can auto navigate to waypoints but wanting to confirm.

Thanks! Byron
