I deleted all my waypoints on both units as well
No voltage issues
Both running latest update
12" on bow didn't freeze but it only does it once in every 5 or 6 trips out so wasn't surprised
10" on console froze twice during a 4 hour trip which is no different than with the waypoints
Doesn't seem that these are the issue
strange that they would think a waypoint would cause the sonar to freeze I need to check next time to see if the chart is frozen as well
