Navionics Chartplotter SD card-no more depths

This doesn't make sense to me at all.

Did you recently update the chart or any firmware on your chartplotter display?

The depth should be coming from your transducer. Not something that is coming from your map chip. There are settings on what is displayed on your fishfinder/chartplotter. I would guess that either the setting somehow got changed or perhaps your transducer has failed after 14 years of use.

Burgerunh, I think his transducer works, it's the superimposed topo map lines and depths that are missing I'm guessing. The numbers he is looking for are; what is the depth a quarter mile ahead and all around your position. I have heard of this with some of these chips. I have a very old Navionics chip that works really well, so I'm not sure on what they did with yours. Just curious if there might be a setting (there are a ton of them) that would remove those superimposed depth numbers and topo lines? Wish you luck.

Hi All,

I will go into the settings once on the water again to check what may have happened. Generally speaking once I have the unit set to what works for me and what I need to do I leave it alone. Once in a while under special circumstances-rare though-I do change settings then set them back the way they were.

- As to chart updates/firmware update I have done nothing since an "upgrade" quite a while ago that gave me DI-Down Imaging. H-Birds in the past, perhaps now still, had a nasty habit of bricking on you when an update was tried. Bricked means send it back to the factory for a factory re-set. Not sure that is still the case but it was enough for me to leave it alone unless I had a good reason to update the SW;

- As to Depth read-outs the chart provides depths that appear on the actual chart itself; the Transducer creates actual real-time depths that appears at the bottom of the screen under the boat regardless of whether I have a chart card inserted or not.

Thanks.
