Hey Pat

We don't do installs here at Radioworld. However if you have 2 HDS units the networking is very easy. You can share Waypoints, Sonar, and GPS all through Ethernet which is a 1 cable connection. All you need is a Lowrance Ethernet cable linking the two units. It would plug into the Yellow port on the back of each unit.

Added the StructureScan in the future would be very simple...it just requires another Ethernet cable to the StructureScan box
