Is the new ACU400 compatible / interchangeable with an ACU400 also from Raymarine but from 2003 ?

Dear Jose, We have had the ACU400 course computer in our product range since 2014. Its predecessor was called SPX30. If your course computer actually dates from 2003, you will need to replace the entire autopilot. Only the drive can remain, provided it is in perfect working order. It is best to send pictures of the labels on the devices to [email protected].

Hi, I'm thinking of buying a new autopilot, raymarine acu400 can I connect the raymarine acu400 autopilot to my b&g zeus3 plotter, via NMEA2000 and get full benefit of the autopilot on the zeus3 and can wind data from CV7 be accessed to the acu400 via NMEA2000 directly or is there a converter that needs to be used finally, maybe it's wiser to buy a b&g H5000 autopilot Mvh michael
