I am needing to replace my EM-2 system. I fried mine! I need a 2006 or later unit that has the 3 connectors on the back of the metal box with the display screen on the front. If you have one you are not going to use, please contact me. I have no idea what they are worth but without it I can’t fly my aircraft.
