So the CX-7 receiver will work with the CX-9? What about models for other Mazdas? I am guessing that the limitation may be the connection cable from the Sirius receiver to the HU? Does anyone know if that cable comes with the receiver or the install kit? I have seen Mazda3 receivers for $140 and the CX-9 receiver is still pushing over $250.... I really want to "activate" the Sirius, but I also don't want to spend more than I have to if the receivers are the same and I can purchase a separate connection cable (if it is even required!).
Thanks!
