EV-100 new out of the box does not work

System set up as an ACU-100 basic system. No other components connected. Comes up in standby. Menu gives 3 options: MODE,RESPONSE LEVEL,& PILOT VIEW. No other options. originally ACU unit came up solid green, now red then 2 short green and then solid green. From day one there was no dockside wizard or any wizard. Compass heading is 50 deg. off. moving the EV-1 flux gate makes no difference. Tried to cross the Caribbean sea from Bonaire to Porto Rico. At first it seemed to hold a course in spite of being 50 deg. off, later that night it started hunting 15-20 deg. left, then right. 150 miles out and 300 to go we aborted and returned to Bonaire.
