Hey Greg, I am sorry it has taken me so long to get back to your response.
I am running the updated software 7.020
No I made all my adjustments to the settings way before this happened and the unit worked like a charm until November.
Again this only happens when I first turn the unit on...the Sonar, DI and SI screens (I am using Amber1 on the DI & SI) simply show a solid color and as the screens scroll across the data remains the same showing no structure. If I do a factory reset everything works great even after I go back and change my settings back to the way I had them before.
I did call support today and spoke with T Denson. She suggested that I turn the unit on move the boat 50 yards or more and then do a Snapshot Recording of all 3 screens and email them to her. I will attempt to do this Sunday Dec 7th and email her the results.
