Did you need to replace the factory radio? I want to install a Sirius satellite radio but VW tells me they don't have a wiring kit for the Eos and the factory radio would have to be removed.Thanks everyone. After research I learned that the factory antenna is mounted in the center of the dash against the windscreen; where there is a small rectangular cap. I've attached the sirius antenna with some sticky stuff to the cap and all is well.The radio was full-bars for a 400 mile round trip to memphis and back this weekend.
Again, thanks.
