Jason,

Thanks for the quick reply!!!

When the issue began I had a file of 684 Wpts loaded. I deleted that file, purged the memory on each locator, and loaded 2 more files for a total 856 Wpts. The 684 Wpt file did not delete correctly with a "Delete All" command. It had to be deleted from 2 different locators before waypoints no longer appeared on all 4 locators. Both uploads populated all 4 locators from a single unit, but at a slower than typical rate.

All the waypoints are backed up, and I have saved Settings files for each locator. I was going to do a Factory Reset next if no other options were available. I just hate to do that because the Settings files do not work perfectly. They will restore most of the overlays and network settings, but not all of them and a few hours will be required to get each locator working again. I have been this route before on HDS systems in other boats.

I am not sure exactly which sonar settings you are referring to? Network sonar is not checked on any of the units. I am sharing sonar data between the units via network settings and overlay data. This is all working correctly. Only the waypoint addition and deletion is in error.

Knowing the HDS memory is a composite share between waypoints (small file size), screenshots, and logs, I cleared all of this data from all of the units and purged the memory of each individually. I removed all the map chips. Then I began running waypoint trials with the creation of Wpt 001. I could create a waypoint across all 4 units most of the time, but not every time. The system would never delete a waypoint on all 4 units...maybe 2 at best, even with an empty memory.
