So, I am a short step away from a great car experience with my iPhone. I just bought a bluetooth car speakerphone which is amazingly loud and clear, definitely worth the buy. I also bough a iPhone mount which holds my iPhone just over the air vent. The final step now is getting music from my iPhone to the car, easy enough right? WRONG! I have a JVC head unit that was installed in my 2003 Cavalier that had an AUX port on the front for easy iPod connection. I went to Best Buy to get it installed into my 2006 Chevrolet Equinox, and the guy said that since I had the antenna and the wiring harness still, all I'd have to buy is a new spacer. At this point, I was thinking that this is going to be awesome! Well, it turns out that the old wiring harness would not work in my new car because GM changed something about the way radios are powered up. OK, I asked him how much the wiring harness would be...it turns out that it is a special order and costs $175!! WAY too expensive, considering that is a little more than what the head unit cost! The Best Buy gut then tried some other solutions but couldn't find a cheap way to do it because of the radio. I do not have XM or OnStar or anything else special, can anyone help me?
