Hey Ken, My unit did this same thing.. I unplugged all the connections, replugged them and it has worked fine ever since??? ..just my personal experience...
Hey Raymond,, Are you reading this when you are at home or in/on the water? Is your transducer in the hull or outside? Do you have the correct transducer?
Please check these and reply back to me..Thanks!!
Its not the scale,, its the settings.. are you using a Navionics card or the built in map... there is a setting to tell the unit which one you are using.. the navionics card needs to be told what section of the USA you are in. Sometimes mine decides I am in North Georgia..(never been fishing there!?).. I have to set it back to sweet home Alabama.
Hope this helps..
peoples eyes see colours differently my advice would be to go through the colour pallet & try each one till you find the colour that suits you will find a stand out colour for you.
Press & hold the + & - key while powering unit on, continue to hold the +/- keys until the unit boots up to warning screen. This don't do it, call support 800-628-4487 and talk to a tech as an "experienced technician". Best luck & good fishin!
