Long time no post....how's it going guys? So I've finally decided to get XM for my car. I have an XM-ready Alpine deck (model CDA-9827), so I can connect the deck directly to the XM unit. I went to a small, local car audio shop earlier today without much knowledge of XM equipment. The salesman said that the tuner (I think he said the tuner) that is adaptable with Alpine decks stopped being produced a few months ago and that I'd able to get it off eBay only. *BUT* he then said that he had a used tuner from his own car that he was looking to get rid of because he changed his stereo 4 weeks ago. He said he would cut me a deal, which included the equipment, antenna, and installation all for $110. He showed me the tuner and it seemed to be in good condition, and he assured me that it works just fine. The tuner was gray and much larger than the XM tuners I'd seen on the XM website earlier, which were black. Being unfamiliar with the equipment and afraid that I was being ripped off, I told the guy to hold onto the tuner and that I would come back tomorrow afternoon to have it installed. I went to Circuit City directly after and the salesman there said the same thing about the Alpine equipment no longer in production, and that the $110 deal was a very good deal indeed. Here is the XMDirect equipment I need according to the XM website: http://www.xmradio.com/xm_direct/aftermarket.jsp The tuner box there looks nothing like the tuner box the guy showed me earlier. And what's this about the equipment not being adaptable with Alpine decks? It says right there that the XMDALP100 digital adapter works with my deck. I'm confused. Exactly what equipment do I need to have XM in my car? Am I getting ripped off? Can someone PLEASE point me in the right direction here? Any help is much appreciated.
