We recently purchased a new car for my wife that has XM built in. But I would like to change it over to Sirius. Is there any way to incorporate the factory installed XM antenna into a Sirius radio without having to install a seperate antenna?
 
With my experience on GM vehicles, I have heard that you loose about 50% signal quality if you use an XM antenna for Sirius signal. I have a Chevy Uplander that has a factory antenna, but it has 2 cables, one for satellite signal and one for the terrestrial signal, and the two cables go into one connector. I found an adaptor that would plug into the factory connector and covert it so it would plug into the SiriusConnect tuner. But it cost $50 and the only company I found that sold it said they quit stocking it because people were complaining about the signal.
