What map for the Southeast States (Al, FL, etc.) can I use in my older Hummingbird 798CI SI non HD model graph? I have the new mapping card for my Helix but need one for the 798 on the console for navigating up and down the river. An older version, etc. is fine. Just need to know which one.
I fish mainly Wheeler and Guntersville lake.
Thank you,
Bill Smith
