Did much the same last year, without radar, the "backbone" cable and the terminal blocks make it easy. You need to run separate fused power to the backbone, the mfd, and to the autopilot. IIRC you need to run a heavy ground from the AP computer back to your main ground. There are adapter cables to link nmea2000 instruments in to the backbone. Rereading your post, it sounds like your instruments are all STng so adapters shouldn't be needed unless you are using chartplotter for data for DSC radio. My suggestion is to think really hard about where you need a second AP control and where to mount the flux gate compass away from interference (speakers, magnetic tools, electric motors, etc) before you worry about cabling. There are a few lengths of cable available, you may be able to place terminal blocks strategically and run spur cables from individual instruments. 2 Instruments can be "daisy-chained" together and a single spur run to the terminal block. Hope you live close to the raymarine dealer, I made a few trips back. Salute to the dealer in Muskegon. In my experience, the iPad will let you check on position and heading etc but you can't adjust course with it. There are more learned people here that can help more than me. I've had some luck with the raymarine forum, they just take a day to get back with an answer. Brad "Pulse" C&C 33 MkII Lake Huron (soon)
