When I go look at the my unit product details from Humminbird website. It say this.
"High Definition 640V x 640H 5" display with LED backlight..."
But on the SPECS section it says:
Display:
5.0" diagonal
640V x 640H
256 Color TFT
What is the difference between TFT and LED ? does my 2012 unit is a real LED screen resolution??
