Installed an "ebay purchased" factory XM radio for '08 A4. Installation went great, radio works fine, but....the word "Antenna" comes up on the Symphony II radio screen. Did I miss something on the hook up?

Three wire-pack plugged right in; only suspicous part was only a green antenna wire, no red. Should there be? I'm thinking it might be part of the grounding, thoughts anybody?

Like I said, radio works fine, all stations, no interference. Stumped!

Not sure if this is the etiology of your problems, but, I used to get that on my OEM player when the antenna wasn't configured properly. Dunno as I don't think you can change the antenna settings through the h/u.
