[CA] Axiom and Analog Radar

Hi I have two questions that would help me if there is a resolution.

1) I have a 2006 320DA Sundancer with Ratheone analog radar that works well with my C80 MDF. I also have a Axion Rayvision MDF, can this radar be interfaced to the Axiom MDF.

2) I have also purchased a CPT300 transducer not installed as of yet. The unit I removed a A78 had a CPT100 which currently is connected to the Axiom. Is there any benefit of keeping the CPT100 installed when I install the 3D transducer?

Thanks for consideration

Russ
