This came out of a Robinson R44 II (24 volt). It was down low in the avionics area and not really much use except for a second VHF radio, therefore I took it out. It works perfectly. It is really a great tool and if i could I would mount it in an aircraft panel where your eyes and hands fall to it. It is a perfect navigation tool, but not much use in the helicopter positioned where it was unless I had dual controls in and someone else flying; then I could take my hands off the controls and put my eyes very low inside the cockpit to use it. 

I can go find the serial number if anyone is interested. I don't believe it is WAAS. Probably needs a database update. I will supply better photos if needed. I don't think there is even a scratch on it.
