I have an H'bird 10 on the bow and a Mega 9 on the console. I have a GPS puck with heading sensor hooked to the bow unit. I also have an Ulterra trolling motor.
My Ulterra is wired to my console unit because it was the first one installed.
What would I need, hardware wise, to hook both units together, both units to the TM and both units to the heading sensor? Or is that all even possible?
