Depending on which head unit your car has (newer ones have front aux inputs) it could be as easy as getting a double sided 3.5 headphone cable and plugging it in that way. But in my case since i don't have that head unit and really didn't want to mess with wiring and ripping out my stereo, I just got a relativley expensive fm transmitter that works really well with the car. And depending on how much money you want to spend, you could buy a whole head unit off eBay or something and replace your stereo with that one which has an aux jack...This may have come up before but is there a way to hook up an ipod to the factory radio in a G6 other then using one of those I-trip things. I mean is there a way to connect it on the rear of the radio (AUX input). Probably not but its worth a shot.
