That card doesn't have TN does it?
This is a Navionics HotMaps Platinum South card. It is approximately 1 1/2 years old and works perfectly. A new one cost $199.00. The only reason I'm selling it is because I purchased a new Fish Finder that included a new card. Call or text Kenny @901-262-2167
I may be getting older but I refuse to grow up.
