[CA] [CA11] Upgrading from an E80 to Axiom 12

[carlmk]

I have an E80 mounted on my sailboat's binnacle plus A/P ST6000+ and ST 60 depth, wind and speed instruments of that era connected to the E80 via seatalk.

I am going upgrade to an Axiom 12 (plus a radar) but I want to keep all the old instruments and A/P. It seems to me all I need is a single converter that converts the sea talk to Raymarine's version of nmea2000 and its output feeds the chart plotter. If that is so, what converter do I use? Where in the sea talk chain should I install the converter?

I plan on using the same A/P head that I have now..

Also, I am not sure wether to add a Sirius weather capability. I might want it later on. Is there anything I should add now that will make it easier to add Sirius later?

Thanks for your help.
