I have a Raymarine Smart Pilot X5 which came with the boat and has been a great accessory to the boat and has never steered me wrong. To Thor’s point though, it needs to be recalibrated (swung) as does my binnacle mount compass. They do get out of whack over time so all compass devices should be checked at least yearly. Last season I added a new Raymarine Axiom chart plotter and an Em-Trac AIS and a new VHS all connected through the NMEA 2000 (incl 0183 or sea talk adapters where required) to connect everything including older ST60 depth/speed and the X5 auto helm. It took a lot of research and rechecking connection diagrams before hooking everything up. To my shocking surprise - everything worked.
Dorothy, take all the information offered from all INA conversation BUT make the decision that suits your needs. Steering mechanisms are great when you want to raise or lower the sail. Or if you want to pack the sail while the auto helm is taking you to your mooring/dock. Or run below to the head. Or let it steer a better course in the fog than I ever could. Or as I like to do sometimes when single handing, let it steer while I stand on the bow looking at the beautiful ocean and sky of the horizon ahead. (and yes I am usually tethered in with my inflatable vest).
Happy sailing!
