Re: Stoopid lawrance
that model is discountinued...lowrance sometimes will not repair them..they offer a upgrade...to a newer model...your unit and cash for a newer model....
make sure the the connections are clean...the power plug..the transducer and the GPS puck if u have one....wipe connectors with alcohol plug them in and make sure the connection is tight....A loose contact does strange things,,,,I know...lol.....
