For some reason, these units frequently get totally crapped up by water damage.  It appears that water runs down the wire harness and into the connector.  Eventually it gets into the unit and causes a failure.  This unit shoes shows corrosion to the corrector, however internally it looks perfect.  30 day warranty.
