Has anyone had a lakemaster plus midsouth south navigation and mapping SD card to just quit working?

The cards don’t have any parts that “quit”. The Sd card reader on you graph is either set incorrectly or it is functioning incorrectly.

I had to use my helix 10 sd card to work on my new 12 and it did great, by my new lakemaster SD card would not work on either depth finder the 10 or the 12. So you say it is functioning incorrectly what do you mean by that, it quit working?

Look for this view in your fishfinder,...bottom right side says what you have selected...if not what you want, check your manual
for selecting ....

Might try pulling the micro card out of the adapter and try using another adapter

Speaking of Lakemaster, is there anyway to request a lake to get plotted? Worthless on Joe Pool. Can't even show humps much less anything else.

Have to run Navionics on my Bird to get anything of value.

Try removing the card and checking the contacts. Using an eraser on them will help clean them and then blow into the slot. Sometimes dust gets in there and causes an issue and this usually fixes it for me.

I don't understand their mapping. How is it Lake Arlington has a very detailed map but they have the crappy map for Pool? I have to use both cards also depending on which lake I am on. The good thing is that Pool is small enough to mark things and then switch the card back or map your own areas that you fish.

Thanks everyone for your input.
