bought this unit along with the 4000 antenna the end of march. antenna was bad out of the box and unit went bad first trip. sent it in, they said it was bad, of course they did not have any to send. kept after them, they said they would get them 1st week of june. started emailing 3 people last week, (multiple times every day) finally heard from somebody today. now they won't have them till august. sure not the same since navico took over.
