I just purchased a boat with a HDS9 Gen3 installed, it also has Structure scan 3D. I have done some initial looking to see what all is installed, but need some direction in troubleshooting.
The head unit itself seems to be operating as it should (as far as I can tell). GPS/Mapping seem ok, I get 2d sonar seemingly fine. But I get no images on Side or Downscan or 3D. It appears I have a small skimmer transducer on the transom(I assume for the 2D) and I also have the large SS3D transducer mounted next to it. I've done some searching on here and will list what I've done so far. I have not tried to update any software yet.. which may be the issue but wanted advice first as I've read about different problems with different versions.
I've done a Hard reset on the headunit, (I had nothing stored in it and figured it was best to start from scratch with some things not working).
I read about the x-ducer cables not being connected properly in other SS3D threads, I checked and did have to swap cable 1 & 2.
I tested it all yesterday and still no SI,DI or 3d images. But now an added item, when I select the 3D unit as the "source" it will start then go to "sonar stopped" on its own. Lights on 3D box are on and green, but x-ducer lights are blinking indicating they cannot find bottom.
Any other physical things to check?
Should I go ahead and update both units with the latest Software or another version? Where could I get a non current version?
the unit I believe has 16.0 ? I cant remember whats in SS3D, I'll add that when I can check it this evening.
