I'm desperate. I bought the aai gm12 but thankfully didn't bother wiring to my sunroof yet. I wanna know for sure someone can get the audio through somehow without doing all that work. The dealership said it'd be around 75 dollars to look at it but I'd really prefer to know how to do it or steer them in the right direction at least so they don't tell me all the crap I already know doesn't work. Blah!
