Thanks TG! I have one of these systems and it only works one-way because one of the wires is not connected. With no schematic, I hadn't gotten around to troubleshooting it. Your manual lays out the wiring which saves me the trouble of trying to figure out what went where.
My only issue is that one side of the cradle on the flybridge broke off so the headset falls out every time I hit a wake or some swells. I think trying to find a new cradle is going to be tough so, if I can get it working, I'll have to fabricate something....
