Hi Kim...like you I am a new owner of a 2002 SC430. My roof opens in about 20 -25 seconds. As for the radio, mine came with the CD inoperable and I had the local radio install guy take it out ( 15 minutes and neat as a pin the way it comes out). From there to install a sat radio component should be a breeze, although I do not have a sat button on my radio either. As for a car club, well I live in Nova Scotia, and I could form my own club by the way everyone wants to talk about my car!!
