With NASCAR going to Sirius from XM I thought it would be a good time to switch to Sirius. After looking at the Stratus I couldn't find a jack that I could plug into the AUX on the Wing radio. Asked the clerk about this, and he said all Sirius radios were modulated, it had to be played through the FM radio. Anyone know if this is true? I haven't had very good luck with modulated radios, seems there's always a staion over riding. how do you guys with Sirius radios handle this? Is it a real problem?
