Alpine Guru's

I've had a CVA-1004 for quite some time now. I had an Apline changer and a XM hooked up. recently I pulled it out of that truck and re-installed into another truck. But after that neither the XM or the changer will work. Well, the head unit's screen will show all the proper information, but the sound doesn't. I even hooked up a DVD player, which will show the movie on the screen, but once agian no sound. The only thing different I did was to add a longer AI net cord between the head unit and the changer. Any ideas where to start? Oh let me also mention that I pulled out the CVA-1004 and hooked up a a CDA-7873 that I had laying around. The same problem is happening on that also...............

Thanks for the help. I just figured out the the problem. The wire diagram from the wire adaptor kit was incorrect. They say the stock harness wire was power atenna when it was in fact the stock amp. So while in am/fm mode it would the head unit would supply power, but when switched to xm or changer, the radio wouldn't supply power to the power antenna shutting off the amp!!!!!
