(DG) Axiom and older wheel pilot and displays

I'm hoping to go with and Axiom 9 and wondering if it will recognize and/or interface with my ST4000+ wheelpilot. If so, what features might I expect to get on the MFD ? I understand my ST60 displays will work with it as well should I choose to keep them ? Install is on a 36' sailboat built 2001

Thanks in advance for your help
