I got a 400 tx that came on my boat and I cant get the side views to work, it says when I power it on that the tribeam transducer is connected and I have gone through the menu to select it but when I hit the view key the only view I get is down, anyone know about this unit, do I need a new tranducer? I know its an old one but I would like to try and use it to some degree.
