Currently I have a HDS 7 touch at the helm networked to a hds 5 gen 2 at the bow, they are linked together with a network cable to share waypoints and the side imaging.

I was thinking about purchasing a used gen 1 HDS 10 to replace the HDS 5 gen 2 at the bow but I Have a few quick questions I am hoping you guys can answer.

First question is can I link the touch unit to the gen 1 unit like I am currently doing with the gen 2 hds 5?

Second, do the older gen 1's use the same power cord as the gen 2? So if I did purchase a gen 1 unit to replace the HDS 5 gen 2, would I have to run a new power cord for the gen 1 unit or could I use the old power cord from the hds 5 gen 2 unit?

I am just trying to make sure that I can just remove the HDS 5 gen 2 and mounting bracket and really just put a gen 1 HDS 10 or so in its place without having to rewire everything.

Only reason I am thinking about this is the gen 1 HDS 10 units are starting to get really cheap, like $600 or so for a used gen 1 10 inch unit.
