Crutchfield Customer Review (What's this?)
Absolutely exactly what I was hoping to get. Easy instillation (I'm not a beginner though) only issue was I couldn't find a spot to place the converter box but I managed to find a little hole for it. Great product. Fast shipping, best price too. Love it.
Pros: Perfect fit, easy instructions, works perfectly.
Cons: Hard to find a place to put the converter box. Put it behind the AC controls and run wires through the back to it.
