I wanted the 785c2i, but when I ordered the store screwed up and didn't place my order till the next day. The warehouse shipped all the 785c2i before they could put my order in.
I ended up with the 785c2 ($220). It does not have the navionics bundle with it. It is external antena which comes with it. Also I have to run the power cord anyway, so running a gps antena cable will follow the same path down. That is fine, when I upgrade in a couple of years I can move this to the cabin and not have any problems with reception.
I haven't used it yet, but the maps that come with it may be enough for me. When I use it in a couple of weeks I will know. I am considering buying the silver maps which cover all US coasts and the bahamas, but I will wait until I need it. ($130)
One thing I wish this thing had is a glass screen. I bet the plastic scratches so easily. I will try a screen cover, hopefully they don't degrade the view. Also it didn't come with a plastic full cover when not in use. ($20 including shipping on ebay)
If the depth contours and depth readings are the same in the maps that came with it and the gold maps I will never upgrade. That is all I really care about as far as the charts go. I don't need any hot fishing spots, inland lakes, or phone numbers to differnt ports. Maybe the graphics look better, I am not sure. Recess has both maps maybe he can tell us?
