[CA] axiom 9 rv to i70s

I have the axiom already, but wish I had gotten the 12. oh well! I'll be installing the rv320's this winter.

Looking at the i70s as a data display playmate to the axiom. This will be large enough to see AND keep it off of my chart.

Rather than me listing what I think, can you give me a parts list to accomplish this as well as the hookup?

Thanks!
