Thank you for that information.
This problem is a failed electronic component called an EPROM.
When this part fails in this way, the Humminbird wont be able to fully load and will shut down at that point.
This can be fixed by Humminbird for a flat fee;-)
The best place to contact for this is listed in your user manual and with the warranty card that came with this one. But if you dont have that info handy you can reach them this way:
