Thanks Greg. My son came by and picked up the unit to try again since he was headed back to where the boat is. He said he was going to try the Self Diagnostic menu and anything else we possibly haven't tried. We will put off the updating and see about getting a new transducer. We don't know anyone else who has this model depthfinder. Greg, what is the model/catalog number of the transducer we need?
Thanks so much.
