What will I need to link my console and bow graph? I have a hds8 gen 2 at console and a hds5 gen 1at the bow. I already have both hooked up to lss2 box, so I can share waypoints and see the lss transducer in the back up front. What I mainly want to do, if it is possible, is to be able to see my map chip, which is in the unit on the console, up front. Or will I have to buy a second chip? Also I have never updated either graph if that matters. I'm assuming the I need to connect via nema 2k but I'm not sure what all I will need to purchase. Any help will be greatly appreciated.
