I just bought a new car, and there’s what looks to be a jack labeled “AUX” in the front of my stereo. What is that?
That ”AUX” input is an auxiliary input jack that accepts MP3, DVD, cassette or CD players when plugged in with an appropriate auxiliary cable, which you can buy at any electronics store for about $5.
The cable will plug into the headphone jack of your portable device and connect to the stereo’s AUX input. After switching the stereo to AUX mode, just like you would from CD to AM/FM, you’re in business.
However, just because the device is plugged in to your stereo doesn’t mean you can control it with the factory stereo’s track and scan buttons. If you want to do that with an MP3 player, a more expensive option is available, usually in the form of aftermarket components. As time goes by, though, more automakers are offering factory-installed options that let you control your MP3 player through the stereo.
