We upgraded to a GTN750, and all this stuff just came out. All was working great. Need to clean out the spare bedroom of this stuff. All these things come with trays and connectors as well. 14V aircraft, everything here is 14V, with the exception of the KLN-89B and the Garmin stuff. its dual voltage. And there is no warranty per se, but your money back on anything that doesn't work as it should. I don't sell things that don't perform.
