Think you'll need an NMEA2K

Think you'll need an NMEA2K connection for that assuming the 2009 has NMEA connection.

Ethernet only replicates the screen I think.

Get a starter kit online and needs a power supply (small), not a big job.

Prob about $200 or so in parts, think I may have enough bits left over from my boat to do that?

Depending how far apart they are (and assuming thats all you want on the network) you'd need 2 short leads, a T piece and a power input.

If you can wait 2 weeks I'll check what I have, say $100 posted?

The older you get the more you realize that no one has a f++king clue what they're doing.

Everyone's just winging it.

 On my two lowrance sounders with ethernet they share sounder pictures and all waypoint information.

Earthnet cable

I had the same setup and all you need is the earthnet cable with the yellow ends. Will allow you to mark on the sounder to give you GPS marks on the GPS if thats what you are chasing.
