Routes disappearing

[Dr. D]

Last year I had my sailing club’s race courses in my B&G Zeus3 chartplotter. There were stable. Today I went to enter some changes and I found over half were gone. I then entered 20 courses. Checking an hour later and most of those had disappeared.

Have other had this problem? What the heck could it be?

Defective micro sd card?

Is the loss of data in this manner a fault mode of these cards?

I tried removing the card and reinserting; no help, still drops routes.

Odd, the waypoints are unaffected.

pretty sure waypoints routes ect are not stored on the card. they will be stored internal.

they can be manually copied to the card to transfer or backup. but that is not where they are used from.

Ouch. That sounds worse.

999 is right. The data is stored in the unit. The data can be moved to a microSD card, but this is a user initiated action, not an automatic function.

I was able to talk with a tech at B&G. Very helpful. He believes the software has become corrupted, though he could offer no reason why this would happen.Steps to take:

1) Backup all settings (waypoints, routes, etc.) to a microSD card.
2) Update software, even if latest version is on the chart plotter.
3) Test. If fails (routes still disappear), then factory reset.
4) Test. If still fails, call back B&G.

I will from now on backup all data on the device whenever I add new data.

At the boat today. I had to do steps 1 through 3. After that the unit was working properly.

I have no idea how the SW on the chart plotter got corrupted, but it did. It was a bit of chore getting all the settings back to my normal after the factory reset, though that part of the menu structure is relatively straightforward.
