Depth finder problem after update


I just completed an update to 3.01 and everything seemed to be working ok except now the depthfinder screen and the dpt information are not in sync. The screen or chart of the depth reads correctly in the graphical display, for example indicating a 5 foot depth but the numerical readout in the lower right corner will read --- or 1 and the numerical readout next to the HF or LF will read 6.6. Any ideas? Worked fine before the upgrade. The depth information on the other information boxes also reads --, just a line.
If you didn't back-up your settings and restore them after upgrading, your settings all were set back to factory default. You will need to ensure your data sources (under inital setup) and depth/keel offsets are all re-entered.
