I have 2 hds gen 3 networked , 9 on bow , 12 on console , external antenna on the stern,
I need to check the 9 to make sure it is using it's own internal antenna , not the external . It appears that some
of my recent waypoints are 20 ft off ( which would happen if I marked the waypoint on the bow unit , but it is
using the rear antenna)
Help ?
thanks
