    Hey gang,

    I bought a used boat with the 858c in it and am having trouble getting my lakemaster pro V6 to register. Could it be as simple as updating the firmware on the graph itself? I did test the chip on multiple units and it works in others.

    Any tips, thoughts, suggestions?

    It won’t hurt anything to update the firmware.
