I think I can help with your issue. I have an LMS 334c and have had a few issues in the past. Called the factory (this answer is not listed any where in your manual) and they instructed me to "Soft Re Boot" my unit and it would put everything back to factory settings. Try this anytime it does not respond for whatever reason.
Turn the unit off.
At the same time press the Pages and Power button. Hold both down until you see the square box come up in the screen. You should have your factory settings again. May need to try a few times.
Lowrance said it works just like a computer, ever now and then it just tries to disect to much information at one time and hangs up.
Good luck. James Cantwell
