I currently have an after-market Sony car stereo system installed in my car and it gets the job done. The biggest reason why I went out and got an after-market stereo put in was to be able to have iPod integration. My car stereo didn't come with it and it doesn't have a USB port either. The Sony system works well and I connect my iPhone to it each time I'm in the car to either play songs in my iPod, Pandora or the SiriusXM Satellite Radio app.
