The unit was also freezing up and shutting down occasionally. I spoke with Humminbird and they had me remove the waypoints from the unit. This solved the freezing up. She also recommended going back to the factory defaults, since the update to version 1.840 was installed. I’m going to try this to see if it helps. I’m not concerned with the adjustments being different, but I don’t feel like I should have to keep the mega setting on 20 the majority of the time, when in the same areas before I didn’t have to. We’ll see what happens.
