Whts up everyone, just recently purchase a 05' g35 coupe. Love the ride, the only problem is that it came w/ a headunit that seems to be jammed and when I turn on the car, it makes a noise as if the cd changer is switching discs from one to another. I only can use the radio for now. Read online it was a common. Any suggestions on how to fix it or should I just upgrade the whole headunit?
