Captain Paul's response ~
The Humminbird 386ci-Combo is considered a LEGACY ( Discontinued) product. See http://www.humminbird.com/Products/386ci-Combo/
As such accessories will be getting scarce and in some cases impossible to obtain. I recommend that you get what you need ASAP.
This also applies to the available mapping software.
The Humminbird web site indicates that the Navionics GOLD, Plus, Lake maps, and Hot maps will work in that unit, but these are marine chart type maps for area where there are established marked marine channels.
The lake maps contain some of the Louisiana lakes, but it is mainly designed for the Bass circuit lakes.
I suggest that you visit a stocking Humminbird and Novanics mapping dealer and actually view these maps to see if they meet your needs.
