Hds gen 1 5 & 7

I have two questions,

1) what's the navionics card that will give me the most amount of detail in the delta ?

2) do I have to buy two cards, I already have the units link with an Ethernet cable I'm not sure of my software version.

Thanks

I can't answer your Navionics question, but the answer to #2 is; Because you are using Generation 1 units you will need to buy two cards.
