I have the Premier DEH-P430 Head unit, the GEX-P900XM Sattelite tuner, and I don't know what the changer is. I'm guessing the XM tuner is probably the same now but the head unit I have is no longer available. That's Ok though because the new Premier units have better preamp outs and such. I bought this system last December so I've had it pretty much a year now with no problems.
