[CA] Axiom added to a67

I currently have an inboard fishing boat with an a67 MFD, Airmar transducer and Raymarine digital (last generation) radar. I just purchased an Axiom 9 RV with RV-320 transducers to add to the mix. Both units have Navionics+. After installing the Axiom can I just network them together with a simple SeaTalkng cable to share radar and sonar data interchangeably across both? Does this give me the best installation or would installing a SeaTalkng network give advantages?

Thanks!
