Joey, I'm curious. I've never seen one like that by ARC/Cessna. I searched through my Cessna Avionics installation CD's and find no mention of an eyebrow mounted "ARC 3" receiver. Only remotely mounted ARC 300/400 units, like the one on Ebay, which uses a separate light module mounted in the eyebrow. Is there an ID plate on it?
Again, just curious. Trying to learn, here.
