OK, I will start looking for some compatible unit to borrow. Hopefully crosstesting will resolve this. Is there some list of compatible units? From user manual, it looks like my 598 is compatibil only with  Xnt 9 Si 180 T.

Your installation looks fine for your boat hull style  ...

There's not much else you can check without crosstesting another known working xducer or head unit  ...

My display and top of unit get warm to touch.
 Yesterday hit a bump and it shut down, would not power back up. Pulled power plug hoping to reset, no go. Got home tested power, it had 12 volts. Tried to power and it worked like it should. Could not make it repeat problem.
Today, same thing, shut down. Noticed display and top of unit was warm to touch, never noticed this before.
Pulled power and reconnected, when I tried to power up, the screen would show a faint flash, messed with for 15 or 20 minutes, would not power up. Gave up, about an hour later pushed power and it powered up and worked. In diagnostic screen, it shows 0 voltage.
I'm guessing I have a bad connection in the unit.
Anybody had this problem? Can it be fixed?
Any tips on opening unit?

Finally I made it to the lake. After today testing, I'm not even a bit closer to solving this problem. Only ting I can say for sure is, that's not electric interference, it is not cosed by boat tilt, or trolling motor turbulence. Water was quite choppy from strong wind today. At first, I tried anchor at the bow and run SI without moving. Picture 1. Clutter fill whole right side of SI. It was impassible to hold straight on that waves so I pulled anchor up and start moving on trolling motor. Magically, everything worked great, for couple hours. Then it started to show up again. At first for seconds. Pic 2 And on the way home, the clutter was there once again permanently.   :'( Pic3

THANKS FOR THE QUICK REPLY. I have not changed anything on the Bird, didn't realize it was different here is and example of the coordinates i am trying to enter they have 2 different ones
Longitude -93.319824 Latitude 37.899977
UTM-X 471882.1464 UTM-Y 4194765.5422
These are for a brush pile and the location they have for it. ( These are TOP SECRET ) so be careful with these. LOL.  I don't really have any experience with entering these and don't know what the second set are for.

1,4-1,6 mph, chart speed at 2. Trolling motor is at bow. Transducer is on transom, starboard side. None outboard motor. 
The clutter is there even if I'm not moving at all. When I check the recording in humviewer it looks much worse then in real time. Probably small resolution of 598 mask it partially. I don't made it on water yesterday, hopefully I will succeeded at Monday.

The real oddity with your scenario is that is seems to only show in deeper water  ...

A transducer problem usually shows on one (or both) sides of the SI image regardless of depth  ...

I'm out of ideas unless you can test that xducer on another unit or test your head unit on another xducer  ...
