[CA] [CA11] Boat in a box

[dkn1997]

2008 Robalo and I assume the plotter is original :
Raymarine
-Model C90W
-SEATALK hs network switch
-DSM30 sonar module (not
sure which transducer)
-RD1418D 4KW digital Radome

I'd like to go with the Raymarine axiom 12 boat in a box. comes with a 12" axiom, 9" axiom,transducer,hub, vhf radio (mine is broken anyway) and transducer.

I'd like opinions on the boat in a box setup. It looks to me like a good value as an axiom 12 mfd display by itself is only a few hundred less.

Is this setup compatible with my existing radome?

Will I need any exttra parts to get the axiom to talk to the new transducer? I assume my existing through hull transducer connected to MFD through DSM30 will no longer be used, not sure if thats the case.
