I've had my Cruze for about 18 months and I've had virtually no problems with it. I use the USB port with my iPhone and it has always charged my phone and played my music. Recently ( the past 2 weeks or so), it will charge when I plug it in but it won't play my music. I'm not very savvy with these things so I don't even know where to start with getting it fixed. The only variable that has changed is the weather. It has been in the single digits lately. Would that have anything to do with it? Please help!
