Just got a '04 allroad with the standard audi head installed. I am toying with the idea of purchasing Delphi's SkyFi kit for the home and car. Has anyone out there done this install? If so, any thoughts on a "clean" receiver placement and wiring install? Can this be tied into the existing antenna module on the roof, or is the "wing" just an empty bug catcher?

Thanks All!!!
