Hi I just joined this forum so I hope I'm doing this right. I bought a Mazdaspeed Miata for my wife (2004). It has the Bose 6 speaker stereo. They said it was capable of having SIRIUS radio. Does anyone know what would be involved (effort as well as $$$) to do this? Is it something that only a dealer can do? I have XM on my other car. Could I also make it use XM? Any help would be appreciated.
