I just bought two helix 10 and have been pretty impressed.Navionics are cards you put in with pre-mapped lakes.AutoChart is where you map your own contours. Are you talking about AutoChart Live?Is there something else Im not aware of?Reading the comnsumer reviews on TW, Bass Pro and Cabelas, a lot of people were saying that it was taking excessively long(2-3 months +) to get their maps back(if at all). Seems like Navionics would be a smart purchase since its national maps compared to having to buy different regions with Autochart as I fish all over the southeast. There were complaints that Autochart didnt show contour lines on lake that there should have been and Hummingbirds customer service could give people a legit answer as to why.
