At the steering console I have an hds gen 2 10". This is the unit I always use structure scan on so noticed it here first. All my units are networked together so any can do it. So I checked them as well.

Front has an hds gen2 5" which is primary for waypoints and the auto-pilot features with the motorguide Xi5. Then I have an hds gen2 touch 9" which is primary for sonar.

I tried all 3 and all three display exactly the same thing. No picture. But if you take off the auto depth and set it to 5 it looks like it is drawing a picture but it is not very detailed. As if there are just too big of pixels for that setting.
