Zoom out on maps shuts down unit when 500 ft range is selected. When i zoom out, it reloads and I loose all my personal settings. Put my unit on billbob's boat. Same result. I updated several 997's with the same sd card. My unit is the only one that is dicked up. Can't even verify how the donut does with the update. Yes, defaults were established before update.

This all started with the new undate. I ain't a happy hooker right now.

The only difference between mine and crappie hunters and billbobs is mine has NVB. Their's work fine.

I like the amber 2 colors....

what I presently have is a 2000 dollar 2d sonar.
