BC,
Without a description of what wasn't working for you, it's difficult to give specific advice, but I had a KNS80 for a while, and it isn't really suited for helicopter operations. King have set it up for fixed wing/left seat operations, so the screen is optimised for viewing from the left, and the operating buttons are angled to the left, also. PITA from the right seat of a helicopter, the screen will appear a strange brown monochrome, yet full colour when seen from the left seat!
If you describe what trouble you are having, we may be able to help!
