MFD - Image ?

[finalpursuit]

All of the sudden an image of some type of sea organism has appeared embedded on my screen. No matter what page I bring up, Radar, Chartplotter, sounder, the embedded picture is there. My bottom guy who does my bottom on a monthly basis tells me he doesn't see anything attached to my transducer which is a Airmar thru-hull tilted element type. I have attached pics of my MFD so you can have an idea what I am dealing with. Even when my system is off the embedded picture is visible..

Any assistance that you can offer would be greatly appreciated...
