Can I view on computer?

No Alice, you can't. The only thing you can do is put an SD memory card and put it in the unit and save screen shots for viewing on the computer. To update the firmware and programming, you load to an DC card on the computer and then insert it in the unit. The unit always remains on the boat.

I had the 798CSi, and now have the 998 HD.

I have a Humminbird fishfinder 525. It goes directly in simulation mode and says: No svinger connected... What could be the problem?

If the transducer is disconnected, it will automatically go into Demo Mode.

If you do have the transducer connected, but the boat isn't in the water, the unit knows there is no water and after a few seconds, switches to Demo mode.

Not sure what a 'svinger' is, but if you need more help, just ask. I can also edit the message and change 'svinger' to something else.

I have had both the Humminbird 798 and also the 1198HD. They are great pieces of kit on the water. The 525 is entry level.

My IPad worked well with Navionics untill few days ago, then following problem appeared: when running my boat with trolling speed ( like 2 mph) the screen shows my position on map with the red arrow and...

Go into Settings - Navionics App and make sure that Mobile Data is enabled and also Background App Refresh. Finally, Location set to Always. It sounds like it is not being updated, but just setting your position on opening.

It is not a particularly good app and very basic although I have not tried the Paid version. I have a Humminbird 998 HD Side Imaging and the Navionics Mappind SD Card which gives much better results.

Sc 998

"Application Start Error". Try "Yellow Key", 1, 0, 7, then Orange Key. When it goes into service mode, shut down, unplug for 15 seconds, then plug in and turn on. If that does not work, call service.

Humminbird 565 says its loading

You'll need to take this one to an authorized service center to have them have a look at it. My guess is that the software is corrupt, so it may just be an easy fix. You can try it yourself if you like (if it's out of warranty). Go to and register your sounder. That will give you access to the software updates and instructions.
Best of luck!
