I'm looking at the 788ci and would like some input as to what I'll need to go with it. I am curious as to the difference in the dual plus and the quadbeam. I would also like to know what you all think about the Nav. bundle versus the Hotmap card for my area. What is it that's in the Navionics bundle that I wouldn't get with my area Hotmap? What should I get in addition to the area map?

Thanks for any input you might have.
