Kizashi Club

Ok guys, I'm a long time reader, first time poster. I have a 2011 Kizashi SE (non rf) and like many of you, I cannot listen to pandora through my iPhone. I read a little and talked to the guys at my local Best Buy and came to the conclusion that unless I want to spend $300+ and get me a double din, touchscreen, Bluetooth etc radio, this is the best route to go. Have any of you tried these? I searched on Amazon and found one for $28.60 (new) and I had a $25 gift card. If all else fails, I'm out $5. My question is, is there a way to wire this thing and use the XM button as a source to power it? Or is my only option to use a designated fm channel as a signal?
