So why ain't anyone built an out put jack for hooking up a 2nd monitor" What about using a wi fi card in the slot will that be able to wi fi out video? I miss so much out on the water and when I get home it is like check that out I should have stopped and fished that! Kind of weird that a 19" monitor only cost $100 yet a 10" screen cost $1500 more than 5" on the fish finders????
