The Navionics Hot Map Premium South is a good map but you'll need to do an update on it ( don't know the cost but you can find out on the Navionics website ). I'm running the Platinum South on my Helix and love it. Don't know what lakes you fish but the boat lane chips are good as well as the Tommy Martin map chips. You can put the map cards in the unit and it will show up but you have to default it under the NAV drop down. Not doing a great job of explaining it but maybe Wayne P. will come by and help you more. He's the Bird guru on here.
After I bought mine I took it to David over at Shut Up And Fish and had him set it up. Good luck.
