Steering system upgrade?

[JFSteimer]

Have Hynautic dual station on My 1973 Hatteras 43 DC. Will not work with my Garmen autopilot. What steering syst. should I upgrade to? Put Garmen 5000 and network with autopilot 12 yeats ago but never tried to set up the autopilot until now. With my upcoming, solo, first trip down the ICW I need a working autopilot. Any advice on a new steering system?

I'm confused with "will not work with" .
What system do you have that would be different from many other installations as to not work?

Your post offers no information for anybody to work with.

Pretty much every boat under 100’ out there uses some variation of hynautic steering. All you need is the correct pump to send fluid to the cylinder. Maybe you have the wrong pump but with no details it s impossible to suggest anything
