So I just linked my 2 Helix 9 gen3s with a new Ultrex. When I shut off outboard to fish I always put console unit in Standby . Now I continually get a message on my bow unit "SI signal lost....shut down yes or no. Doesn't matter if I click yes or no it keeps coming back. Only way to get rid of it is to power down console head unit but then units won't share waypoints. Any ideas ?
