navionics maps to it, my problem is that when I was in the midst of trying to make my mind up what unit I wanted I believe I read somewhere that the 587ci only works with certain navionics maps. I have searched around and have not been able to find out. Just wanted to get some clarification before I order. Also anybody got any ideas as to where to buy the navionics at the best price ?
thanks
