Undervoltage problem with 520c

[firebass]

Starting my motor caused my 520c to shut off, I understand the cause is the battery, but now the unit is malfunctioning. The button to access the "pages" menu does not respond and I cannot get to the sonar screen. The GPS menu works fine. Is there a way to reset the unit or did something inside get fried?

You can try and do a soft reset that will not erase any waypoints or trails you have saved. With the unit off press and hold down the Pages button and press the power button. Keep holding down the pages button until the map of the US shows up. Now the unit is reset to factory defaults. If this doesn't help you will need to call Lowrance customer service at 1-800-325-1356.

Worked like a charm! Thank you Ken.
