Topic: 998 shutting down when I scroll to map view

[jdcham84]

Having a problem with my 998si. Most of the time it works fine but ocassionaly it will shut down when I change view to the GPS map, side scan, switch fire, 2d all work fine but then I will change view to the map to run to a different spot and it will shut down and reboot. First time it happened I was running across lake in choppy water and it just shut down. I have to unplug unit and let it set for a couple minutes, I have to do that multiple times or sometimes just once.

Remove any map cards  ...

Then export your waypoints to a blank SD card and open them in Humminbird PC to look for corrupt waypoints  ... Look for odd dates, lat/lat that do not make sense, waypoint names with characters other than numbers and letters  ...

After waypoints are verified in HBPC - reload them a formatted blank SD card  ...

Then in the HB unit - Restore Defaults under the Setup tab and Format Nav Directories (also under the Setup tab)   ...  before loading your waypoints back into the head unit  ...

Which map view and map card were you using? 

[jdcham84]

I was using overhead view and a lakemaster chip.
I followed the previous instruction and saved waypoints to sd card. then resest to default and cleared navigation.  Then checked waypoints for corruption found nothin so reloaded waypoints. Havent taken it to lake yet but it did crash the first time i scrolled back to map. It seemed to work fine after that first crash. I wondering if I shouldn't try to use some di-electric grease on fittings, maybe I'm not getting a good connection

I should also add i never had this problem before I did an update at the house. I ended up bricking the unit. Update worked on the 898csi. I had to send the 998 back to humminbird. They fixed it and did the update. About 6 months later is when problem started I had only taken it out once or twice

If that's the Birds-Eye view then switch to regular chart view.  There have been older problems with that view and not sure they ever fixed it.  I usually keep that view hidden so I never use it.

That's a good idea never really use that view anyeay it's just on my way to the contour view. I will give that a try
Thank you

Let us know if that cures the problem.  Good Luck
