Guys! This is incredible! Thank you so much for your posts and hard work. I'm undergoing a very similar project, but for my Raymarine ST2000, I just couldn't see the point in floating the $550+ for the SmartController, when I can make my own! Right?
I'm planning to make mine using the simple 4 button RF remote and Simple RF M4 - 315MHz Momentary Type Receiver. I really just want to run everything from the mast base (inside the cabin) so the remote should work from the foredeck and cockpit. My boat is just 27 feet. Do you guys see anything wrong with running the cables ~18'-20' from the mast to the cockpit where the autopilot plugs in?
