SD, never fear. As long as it's less than a year old there's no problem (shouldnt be anyways). Look up Lowrance technical support on the web and get in touch with them (probably by email). They should have you ship your unit in and they'll either fix or replace your old unit, free of charge. Do it quick and you should be back in business in a couple of weeks. I hate it had to happen to you, but as with anything electronic there can be problems with any brands. Atleast as far as I'm concerned you have one of the units that carries one of the best warranties. Good luck with it and keep us posted as to the outcome.
