I just got my Helix 7 mounted and hooked up to my boat. (Not the newest model to date the previous model)When I first started it up all I have is this black screen with green writing and can't get anywhere with it. I need some help. This is my first ever unit of any kind so I'm really green when it comes to this all the help will be greatly appreciated.
I can't get the figure out how to post my pics. It says that the pic is too big.
