Good afternoon,
I recently installed a SS module for a friend of mine, I've never used Lowrance HDS or their SS so I am in the dark on setting it up. Upon installation completion I could see a line down the center of the display and select from some options however my friend told me it didn't change from that line down the center when it was in the water. I have the yellow wire from the HDS 9 going to the yellow wire on the SS box, it powers up and I can see the green lights blinking on both transducer connections at the black box. Is there a setting I missed somewhere to activate the Side Scan or Downscan? For source I have selected "this unit" Thanks in advance, I have little to no experience operating Lowrance stuff.
