No more Hummingbird 788ci problem

Since I wasn’t going to send the unit in to get repaired for175$ I took it apart to see if the parts inside might of gotten wet. I workvery slowly till I had all of it part and laying on the table and then I discoverit had a VIRUS. :yikes
So I put it all back together. Then I walked over to thesink and got my wife’s dish washing liquid and apply to the front of the unitand swipe off quickly.
Reinstalled to the unit on the boat and it works fine.
The problem was---------- Sticky Button Virus Rofl
