Help With Humminbird 1198c Issue.

Hi, I wanted to post here due to high traffic and perhaps some of the experts on here could help me out. When I scroll my screen to the map the screen would freezes up before it got to the map. My waypoints and tracks are saved on the map screen. This happened when I was deleting some of the junk waypoints. It froze in the process of deleting. I could not scroll to different screen. So I turned it off and turned it back on. Now it would freezes before he gets to the screen. What would cause this? Corrupted file? I have the Lakemaster and i did try to pulling the SD card out and put it back in. It didn't help. I did powered it off and on. Same result. Help or suggestions are greatly appreciated.

Thanks,
Guy

have your local dealer send it to hummingbird. they are great about quick turn around on repairs and stand behind their products. i am not tech savy enough to offer a solution to that.
