A:Answer It all depends on your stereo, not the car. Every once in a while, my cassette adapter will reject it. I don't mind messing with it until it works. When it works, it's awesome. Maybe your stereo won't reject it at all. All it needs is a 3.5mm headphone jack. I plug mine into my cell phone and play YouTube music and magazines that I've downloaded for free. It doesn't hurt to try it out. I've never had a problem returning an item at BestBuy. I use my cassette adapter almost every time I'm in my car.
